What is your favorite 1 hit wonder from the 70's?

Czarivey - the basic concept of the "1-hit wonder" is that the performer had only one (very good) hit. If your reference to Psycho Killer is by the Talking Heads, it would not qualify, as they had many hits.

Marty---When Edmunds and Lowe started working together on their respective solo albums, they started touring billed as whomever's record was being promoted. That touring Band was Dave and Nick of course, with guitarist Billy Bremmer and drummer Terry Williams (earlier in Man, later in Dire Straits). That is, of course, Rockpile. I saw every tour that line-up did, the shows differing only in what songs were performed and who did the most lead singing. One of Rock n' Roll's all-time great Bands!

By the way, the Rockpile line-up was in place to record starting with Dave's Tracks on Wax 4 album and Nick's Labour of Lust (which is MUCH different than his first, definitely showing Dave's influence on Nick), both from '78, IIRC.

Gimme Gimme Good Lovin' by the Crazy Elephant.

Oh, how about "Starry Eyes" by The Records?
