TPATH was just as crazy as Fleetwood Mac in their drama and drugs. Their old VH1 "Behind The Music" shows a bit of it:
Stan says of himself: "There's only a couple of things you can do to
get fired: suck at it or have a bad attitude-I probably did them both." Interestingly, not long after his 3rd firing, he was picked up by Don Henley and moved into a better career as a producer and songwriter.
As I understand it, he was not happy about Stevie getting Tom's "Stop Dragging My Heart Around" from Tom. He felt it should have been on Tom's album. But he did play drums on Stevie's album for that song. It was written by Tom Petty and Mike Campbell. Iovine somehow persuaded Tom to allow Stevie to put it out and it was a hit. There was probably some friction over that during that time.
The song was pretty much all ready recorded as a TP song. He didn't contribute drums after the fact.
