Strictly for financial reasons. I joined them in early April, after answering a CL ad looking for musicians for a Tom Petty cover band. Six of us answered the ad, and we clicked right from the git-go. After much rehearsing and forming a set list we've played two gigs so far, with a third upcoming in early August. The problem is that I've had no income coming in since my unemployment ran out in May. We're living on what my wife and son bring in, and it's not much, since they both work at Walmart. I've been looking for work myself, but no one wants to hire a 58 year old man these days. I've applied at Walmart myself, so we'll see where that goes. It's sad, but I just can't afford to be in a band right now. I drive an old car that's in need of some repair, and the price of gas isn't coming down much more. We have a band meeting tonight at a local restaurant, and I have to cash in a roll of quarters just to be able to buy something to eat and drink! I'm probably going to tell the guys that our next gig is going to be my last, and they need to find themselves another bass player, preferably someone with a steady income! Thanks for letting me rant. This is tearing me up inside because this is a good band with good musicians. Man, this economy really sucks for us old guys!
