One of the lesser-known groups of the mid 60’s British Invasion was the Swinging Blue Jeans. In 1964, they rocked the charts with “The Hippy Hippy Shake.” The 45 on Imperial Records is now worth up to $30.00. The group saw little success after that. When Graham Nash left the Hollies, he was replaced by Terry Sylvester from the Swinging Blue Jeans. Their most valuable record is the album, “Don’t Make Me Over.” Released on Capitol Records in 1966, it’s worth up to $1,000.00 today.
