Hour late to rehearsal

JOHN: OK, Dan is now officially an hour late to rehearsal.
CHRISTINA: Can't we just start without him, John?
JOHN: No! We specifically need to work on his guitar parts on "Cathartic Target Practice."
RONI: While we're waiting can we discuss what a dumbass song "Cathartic Target Practice" is?
CHRISTINA: It's... pretty dumbass.
JOHN: It's a GREAT song.
