Unwashed and Somewhat Slightly Dazed Lyrics

Cover art for Unwashed and Somewhat Slightly Dazed lyrics by David Bowie

I agree with ramm and gtilleuy, but would like to add that

"I got eyes in my backside That see electric tomatoes On credit card rye bread"

Likely, at least partially, implies LSD use, as it's commonly referred to as "electric", and ergot, the fungus used to make it, grows on rye.
