Gary Puckett released this Paul Simon song in 1971 on Columbia Records. Keep The Customer Satisfied is on both sides of this radio station copy. There are two different color labels on the 45 rpm record. Green on one side and white on the other. The green side says it is in stereo and on the other side it does not specify.
Record collectors know that having a radio station copy that is in good condition and sounds great is very rare. This is one of those.
