This morning a snippet of melody and lyrics entered my head:
(Am7)Everyone wants to feel (D) good.
I played with it a while and suddenly felt an urge to add the chords F and E.
Now, "What other song uses that?" I asked myself. Hmm, there's a similarity to House of the Rising Sun. But that's not it. Then, suddenly, it occurred to me:
Groovin' Is Easy, by the Electric Flag.
So I went to amazon, clicked on the listen link for that song, and there it was. Same key and everything. Damn.
