The YouTube info said :
Frank Zappa gave this record to my Aunt, Miss Christine of the GTOS. Its a rare demo version of one of the songs from the GTOS album Mercy's Tune (I have a Paint Brush in my Hand to Color a Triangle) before Mercy sang it with the full band that Zappa used for the song. Lowell George sang this rare demo.
Written by Miss Mercy. This is a song about a lovers triangle which involves Brian Jones, Bernardo B.T.O and Miss Mercy.
This demo 45 rpm record came from my Aunts personal record collection. Same song on both sides.
