They, thanks for all the replies, folks.
I AM pretty new to playing bass, and this IS the first real gigging group I've played with. And I didn't mean to make the BL out to be some horrible guy or anything lol. He has his moments, but he's a decent guy. As I sad in the OP, everybody gets along well and we tend to play well together when it's all meshing.

You should be able to nail it, after first verse/chorus... when it come around the second time, you should be able to do it. But the important thing here, with the BL, can he take his own medicine? He damm well knows that SOME of the band members knows what he yells out of the blue, but if not ANYONE in the band knows the tune at all, does he still carry on? I've encountered band leaders who yelled out song title, key, and that measures "2 4rs 8ths and middle 8 in C, 2 8 bars!!!" I can't even relate to that. Like an order at a table at a restaurant.... the main thing with ALL these BL's is that they themselves wouldn't hold a candle if faced with the same situation. If they were so proficient at it, they would know that it's nothing you yell out to the others.
I make one thing clear: I don't play for anyone IN the band. No one. Me and the audience first. The BL is the last thing I would play for.
