The Hollies – Butterfly (Expanded Edition)

Bernie Calvert comes as the second bassist of The Hollies, joining in 1966 after the permanent departure of Eric Haydock. When Calvert joined The Hollies, he would use a Precision Bass until 1967, where he purchased a Fender Jazz Bass, in a sunburst finish, along with both a pickup and bridge cover. The bass is popular within The Hollies, as it appears in several Hollies songs and albums from early 1967 to late 1968. Some songs where this bass is most prominent are, Bus Stop, Step Inside, Dear Eloise, Blowin' In the Wind, and many more. Along with the songs, albums such as Butterfly and Evolution has this bass as Calvert's main instrument.

In 1969, he switched from the Jazz Bass to a Precision Bass, but he would occasionally bring out the Jazz Bass in some performances. Along with that, Calvert is seen with numerous models of the Jazz Bass. His main model - which is most likely a 1963 model - can be seen with the covers on (pre-1969 performances), and off (music video for Amnesty). Another model has a lighter sunburst color, and can be seen in the mid-70s, his last model was seen in The Hollies' performance of Heartbeat, and That'll Be The Day in 1980, just before his departure.
