Here is a youtube link the song in question Search and Destroy, released by the Stooges on the album Raw Power.
The web tells me the line is:
I'm a streetwalking cheetah with a heart full of napalm
But I always thought the line was:
I'm a streetwalking cheater with a hat full of napalm?
(On the track, he seems to pronounce it as "hat" requires a Boston accent if it's actually "heart"—Iggy is from Michigan;)
Q: Do the lyrics posted on the internet come from a textual source, such as liner notes, or is it possible inaccuracies have been introduced and codified by the internet?
