Where were you when Boyz II Men was all the rage and then some (when the phraseology of the time went something like, "all that and a bag of chips")?

Be honest, now.

Sitting by the boombox, wailing — some called it singing — to your teenaged reflection in the mirror about how you've come to the end of the road?

Dancing with your girl to "I'll Make Love To You," hoping against hope that you could, or would?

Finding your freshman groove to a cool little Motownphilly swing?

Or maybe you were less emotionally invested in the group.

Still, you had to be living in an alternate universe not to know that the Boyz were big. HUGE. And they still carry some serious pop music clout.

The four-time Grammy-winning foursome is the best-selling R&B male vocal group of all time, having scored five No. 1 singles between 1991 and 1997 and having sold more than 60 million records worldwide.

If you were listening to the radio between 1991 and 1994, you were listening to Boyz II Men.

And you have the memories to prove it.

They take the stage tomorrow night for a — what else? — Valentine's Day concert. Before they do, let us take you back to a time when the Boyz ruled the world:
