Stevie's "stolen" Tom Petty song

[Josh2003]

Just saw "In Your Dreams" tonight (and loved it, of course).

Do we have any idea what song Stevie "stole" from Tom and recorded with FM, only to have Tom demand it back? I know it ended up being Tom's song "Runaway Trains," but this is the first time I've heard this story.

Any idea if this is a song that we've had in demo form? I'm listening to Runaway Trains now, and while I think it has a bit of a "Joan of Arc" feel to it, production wise, it doesn't sound like anything we've already heard (or, at least, that I have heard).

Hive mind, any ideas?
