Have you guys heard the song Rats by The Kinks?
Doesn't have anything to do with the SY song. Except that Dave Davies was sort of the Lee of the Kinks.
Edit: Holy shit, I just searched Allmusic and there are a lot of songs called "Rats":
Syd Barrett - Barrett(1970)
The Kinks - Lola vs. the Powerman & the Money-Go-Round, Pt. 1(1970)
blah blah and so on - interesting ones: Pearl Jam (I'm sure some of you idiots know this one), Billy Corgan, Rasputina (hahaha), etc.
