At various times I have discussed the cover version of "In the Mood" by Henhouse Five Plus Too (a pseudonym of Ray Stevens).
But I've never found a sound sample of the song, which I haven't heard in years.
I finally found a sound sample on this page. (Actually, I found the page several months ago, and just rediscovered it.)
If you've never heard the song, I encourage you to click here (m3u format).
If you don't agree that this is the most beautiful song ever, then you just don't know music.
