Success clearly hasn't spoiled Boyz II Men.
And how do we know this?
The enormously popular harmonizers, who'll turn out the Molson Amphitheatre Tuesday with Montell Jordan and Mary J. Blige still flex their vocal styles in washrooms.
"When we began collaborating (in '88 at Philly's High School for the Creative and Performing Arts), we'd go up to the bathroom on the fourth floor and sing," Shawn Stockman told me three years back. "Washrooms make you sound a whole lot better. I guess it's the acoustics."
Since hooking up, the clean-cut four-whose average age is 22-have sold 20 million copies of their two albums, have bagged a truckload of awards, and boast a fan base that spans continents.
Two years back, they elbowed Elvis Presley off the music history books when their single, "End of the Road," ended up sitting at the top of the pop singles chart for 13 straight weeks. (Presley had set a record in '69 with "Don't Be Cruel.")
But they ain't too big for the lowly toilet.
"Oh yeah!, oh yeah!," responds a spirited Wanya Morris when I asked if the group still sounds off in the washroom.
"We have dressing rooms that have showers and stuff.
"It may be funky," he says, cracking up. "But we get in there and sing."
And leave the place a whole lot funkier?
"Yeah!" he replies, laughing.
Considering the foursome's epic achievements, it may come as a surprise to hear them say they're "not as successful as we want to be."
"We want to be the kind of group that's untouchable Morris says. "We want to have a tight organazation that works on one battery. But it'll all happen in time.
"We consider ourselves babies in this industry," he adds. "We look at Michael Jackson and The Beatles, to be among them is one thing but to be up where they are is another."
Don't misconstrue their ambition as greed.
If one thing shines through in a conversation with Boyz II Men, it's their humility and ultimate faith in the Creator.
"It's easy to keep our feet on the ground because we came up not having much and saw what happens when people who have a lot of money get corrupted or go buck wild with it," pipes in Michael McCary. "We take everything in stride and move slowly with it."
"The Lord, our parents, and families" keep the crew rooted in reality, he adds.
And the reality is these modern-day doo-woppers deliver the goods with an emotional intensity that probably even scares them.
Treat your ears to "On Bended Knee," their cover of "Yesterday," or their interpretation of "The Star Spangled Banner."
"You get scared to do anything over," admits Morris.
"Songs like 'Yesterday' can't be done the way the originals were.
"As for 'The Star Spangled Banner,'" he adds. "You don't want to mess it up by (here he imitates how most of us sing in the shower). What you want to do is keep it simple but make it beautiful.
"And that's what we do by singing a capella."
