I found this on Youtube when looking through the Count Five videos. This cover is from a concert in Reno, Nevada in 1991. Stan Lynch, the original Heartbreakers drummer, does the vocals and it turns out he has a great voice.
I've always had a soft spot for Lynch and secretly believed he and Petty were like brothers which made it difficult for them to get along.
Stan Lynch is also an acclaimed producer and songwriter, working closely with many acts (Fleetwood Mac, The Eagles, Bob Dylan) and specifically with Don Henley on solo projects (aka most of his biggest hits).
This cover is really fun though and worth a few minutes.
