did you know that dolphins are just gay sharks?

I reckon he, AJ and Howie are all around 5'6 *g*. And the only reason they'd lipsync (at least, this is how it was when they were younger as far as I understand) is if the shows weren't set up for live performing. When you watch Euro-era performances for both groups, there's a number that appear to be lipsynching, but the guys normally did an a capella bit too (the we really can sing bit, I think of it as).
