Run by Adam Gibbs. First location was on the site of 172 High Street, Egham (now the site of a Christian Science Reading Room); I remember a (dubious?) fire at the premises some time in the mid-1970s. Shop relocated to #86 High Street some time after.
Interestingly, they used to operate a music library, so you could hire an album, take it home and tape it, then return it a few days later.here to edit.
