The Hollyridge Strings were an in-house act released by Capitol Records. Throughout the 1960's, they were perhaps best known for their instrumental versions of Beatles songs. In fact, so popular was their first album that an album exists by "The Mustangs" whose cover is a take-off of the cover to the first instrumental Beatles album by the Strings. Stu Phillips arranged and conducted the first three volumes, plus the album with solo songs on it. Perry Botkin, Jr. and Mort Garson did the honors on volume four, but Garson alone did the job on volume five.
