my band is playing a show in 2 weeks, and we have a good set laid down, but we need another song. We play blues, classic rock, and limited punk. We are currently playing a blues jam session, rock jam session, and session that reminds me of pink floyds sound. We wanna do a cover ppl will know, but due to our lack of good singing.... we wanna try to get a song w/ limited to no words. Any suggestions?
