In my previous band we did a medley of five different Rush songs mashed together and I think we all agreed this was a bad idea. Ten full minutes of Rush will really make non-Rush fans' eyes glaze over. We also did a medley of "all summer long" with "sweet home alabama" and it made OUR eyes glaze over. However, in my new band, we play Pink Floyd's "young lust" and as we jam out the end we've started to drift into playing "Riders on the storm." Same key, very similar tempo. It's just been a little tease so far but we've talked of actually learning it and playing it for real, going straight into it from young lust. Good idea or bad idea? Part of the reason I'm asking is we're working on doing "Billie Jean" and the instrumental section has proved very difficult to really nail. Our guitar player stumbles over that clean funky lead, and the overall arrangement there doesn't sound very full at that point of the song. Also, trying to work out a good ending for the song has proved surprisingly difficult. However, the verses and choruses sound really good and I'd hate to ditch the whole song. So it occurred to me that we could go into some other song at that point and end with the second song.
