I have been sick all weak. No I didn't have the Swine Flu. No fever but it was a voice killer. I sing lead on about 60% of the vocals. I also sing the harmonies and the drummer and bass player sing the rest. For the first time in 30 years I could not sing a note it was all I can do to talk. I did manage to struggle thru some of the harmonies and kind of keep the other 2 guy's on track for singing my parts. It really caused a very relaxed atmosphere on stage that surprised me. Man we really kicked some arse last night to a packed house. It was a very young mixed race audience and I was very surprised buy how much they loved our CLASSIC ROCK. I play "Do You Feel Like We Do" buy Frampton note for note talk box and all. and that really brings down the house. I guess you could say we took lemons and made margarita's LOL.
