The Refrainers
Create a cover band that plays popular tunes, but only sings the chorus. Most people only know the chorus to pop songs, and you can never understand the other lyrics in the loud, bad acoustics of a bar.
The audience can sing along with the chorus, and the band can jam and solo in the rest of the song.
