If You Don't Come Back/ Think

This was a later (1964) incarnation of one of the earliest British garage rock bands, the Undertakers. Many of the group members went on to work with other British bands and celebrities, including Pete Best, Van Morrison, The Who, Led Zeppelin, and others. This was the incarnation's only 45, the U.S. release. A good history of the band can be found in the Tapestry of Delights.
