My first gig was in Philadelphia and I played the drums for my older brothers. That same night, I also played drums for Martha and the Vandellas. Ah, the fond memories of being 14.
You get to the point in life where you realize you have to roll up your sleeves, deal with the consequences of what happens, and carry your own weight.
It's no surprise to me or the other Isley brothers that I can sing, because I used to sing all the time in practice. The surprise is that somebody else likes it.
