It was canned. Numerous instances, but Ferrone's not playing the snare during a cymbal wash at the end of a song is one example. Canned backing tracks seem to be the norm, but Petty's sung vocals seemed canned as well. I don't care. I was surprised that so many songs (3) were from Full Moon Fever, and bummed they didn't sing "Ventura Blvd" in all that glorious Jeff Lynne-4-part-ELO-harmony in verse 2. My liquored-up lizard brain was primed for that moment and then.... nuthin. Still- fun mini-set.
