OH Jesus yeah, are you kiddin. I always marvel at new band practices when a new lead singer is learnin tunes I played 6 nites a week in 78-94
Yeah, Ill go thru this 3-4 times a yr at least.Now days, its seems someones leaving and someone taking their place MUCH more often than in my road daze forcing the band to re hearse old tunes so the arr. can be learned by the new guy. BUT, I guess being a drummer and having control over intros and endings, I strive for new replacement parts to create interesting arrs' so they dont become boring.Cant really answer to the new stuff except as a bass player, Ive been takin country jobs here lately and the newer country is pretty involved arr' wise so its a challenge.
I play such a mix of genres so it never really gets boring personally, but as a band, it can come off stale. A drummer can kick ass but if everyone else is not feelin the dynamic, it really stands out..

..Some people I used to play with out W where being a human jukebox was prevelent, and you could set your watch by them, those cats deemed it perfectly normal to stay tight on 45 tunes for a yr. They were a diff breed..
Yeah , your lucky if ya getta play more of the free form stuff, not so lucky for a cover dance/ show band.But, yeah we used to get on the elevator and say , Man , Id rather take a beaten than play tonite..

No more than I play now ,I doubt that will ever come outta my mouth again..
