The Checkmates were a fairly popular band around town in the 1966/7 time frame. Although we don't have the whole story yet, they seem to be familiar to several of the other bands and fans from the time. They were listed as playing in college bars around the time.
Famed local performer/writer/operator Kenny Smith wrote a couple songs that the band recorded for a 45, released in August of 1967. The songs are in the Smith style of soulish garage, and solid on both sides. The record was probably recorded at King.
