Worn down piano - Mark and Clark Band

This is one single I almost didn't buy because I thought I already had it. I didn't, but the sleeve looks awfully familiar. I just can't work out where I might have seen it.

Anyway: 'Worn down piano' is one of the most interesting songs from 1977. Split into two parts, the full length of the song is over eight minutes. The lyric tells a story of an old piano that's about to be auctioned off, while a poor man plays the most beautiful melodies on it. The single reached number 8 in the Dutch Top 40.
