They might have a few grey hairs and some extra laugh lines, but, two decades on, Boyz II Men are still setting hearts aflutter worldwide.

Best known for their heart-wrenching ballads and soulful harmonies, the most successful R&B group of all-time will hit our shores this month for their fourth Australian tour.

The band's second tenor, Wanya Morris, says that while the guys may have aged, they still have the moves.

''Oh come on, that'd never leave, I don't think that's going anywhere until I'm in a wheelchair,'' the 39-year-old says.

''Bring your tissues, [and] your dancing shoes … because you gonna have the time of your life.

''We're going to take you on a journey that's an emotional, high-energy rollercoaster, songs that are going to help you get to the place that you were [in] back then.''

Since coming together in the late '80s as students at the Philadelphia High School for Creative and Performing Arts, Boyz II Men have gone on to sell more than 60 million albums worldwide.

In 1992, their first single to reach No. 1, End Of The Road, retained the top spot for 13 weeks, breaking a decades-long record held by Elvis Presley.

Their tunes I'll Make Love to You and One Sweet Day with Mariah Carey also went on to set new records for the longest period of time a single remained at No. 1.

Morris believes Boyz II Men's popularity at the time stemmed from the originality of their music.

He says the group addressed issues of love like no one else had before.

''I think it was a time where people were struggling to recognise a lot of aspects of love,'' he says.

''If you were losing love, that's all it was about, you never thought about the love you could find because you lost that love.

''You don't think about the things that are going to happen because something's lost.

''So the songs gave hope, they gave people the love they needed when they felt like they didn't have anything.''

It was also one of the first times that harmonies, which Boyz II Men had modelled on those used by a cappella gospel choirs, made their way into the popular music genre.

Morris admits that when they were rehearsing in the school's bathroom (due to the great acoustics), worldwide fame and fortune didn't really cross their minds.

''It wasn't something we set out to do,'' he says.

''Being able to add those musical structures to the sound, it just made sense. It wasn't something we struggled to do, it just came naturally because we were all of the same era and we all loved music in the exact same way.''

Boyz II Men can also lay claim to being one of the first boy bands, with several others popping up after their initial success. Morris says the term ''boy band'' didn't even exist when they started performing together.

''I guess we were the first people that groups started modelling their songs and music after and they just so happened to be boy bands,'' he says.

''For us, we just wanted to get our singing group signed so we could get our music across. As record companies started trying to build groups that could actually do the same thing and sell good music … they actually created boy bands.

''They found … young boys who could sing and looked like they could be on a soap opera. They put them together and made them America's sweethearts; and they could sing their assess off, so it just happened to work!''

While other such bands have come and gone, Boyz II Men are still working together and producing new music two decades on.

They tour regularly around the world, and their most recent studio album, Twenty, - which contains the group's first original material in nearly a decade - was released just last year.

Morris credits the group's great relationship with the longevity of Boyz II Men.

''We're more than friends, we're brothers,'' he says.

''Friends fight and then they're not friends any more, brothers fight and you can go on stage with them and still have a great show.''

After their Australian tour, Morris says the group will again head into the studio, with plans to create yet another Boyz II Men album.

''We realise and we feel like this album has to be epic because it marks a milestone and a completion of what's going to happen next in our career,'' he says.

''We're really excited about it.''

Morris admits, however, that the group's '90s hits are the ones that get audiences most excited.

While their popularity was undeniable at the time, he says the meaning behind the tunes is still relevant today.

''It was just the time, the songs, the sentiments behind it, the vocal inflections,'' he says.

''Everything was supposed to be the way it was because the stars aligned.

''But you can still feel that same connection when you're performing those songs today.''

Just this year, Boyz II Men were recognised for their contribution to the music industry with a star on the Hollywood Walk of Fame.

Morris says that moment meant a lot to the group.

''It felt incredible, just to think that … 60 years after we're gone, our grandchildren can go over to that spot and say 'this is my grandfather','' he says.
