I'm currently playing in a funk/soul/rock group, and it's tons of fun... The problem I've run into, is that the band leader has been introducing new songs, and I came to the startling realization that every single song, sans none, is based around the exact same progression: I-, bVII and, if there is a bridge, it's almost certain it will be I-, bIII, V... What do I do? Do i get the singer to rewrite the songs? Do I shut up and play? How do I maintain diplomacy? Any advice?
