If anybody can help me with this, the members of this list can...

I'm looking for the exact release dates of several records from the '70s. I'm pretty sure all of them are from 1974 or thereabouts, but ideally I'd like to find exact release dates (or at least months). I have an old cassette on which snippets of all of these can be heard, and I'm trying to determine the earliest possible date on which it could have been recorded.

The records in question are:

- "The Streak" by Ray Stevens (single)
- "Energy Crisis '74" by Dickie Goodman
- "Cinemoog" by the Electronic Concept Orchestra
- "Music Power" compilation by K-Tel

Anybody know where to look for this kind of information?
