Greg Todd & The Jacks - Love (Holiday Inn 2202. 1968)
Holiday Inn was a Tennessee label started by Sam Phillips with money from the RCA buy out of Elvis' contract. Unsuprisingly they released a number of country 45's, as well a few rock goodies such as Greg Todd and Portrait of Fun.
Memphis based Greg Todd & The Jacks also released the excellent Love Transcends/Garden Of Delight 45 (Holiday Inn 2217), which is well worth tracking down!
This is the Country Joe & The Fish song, and while not as good as the original it's still got a charm of its own, and suprisingly rare to see a CJF cover.
