In August 1964, Dickson managed to acquire an acetate disc of the then-unreleased Bob Dylan song "Mr. Tambourine Man", which he felt would make an effective cover for the Jet Set. Although the band was initially unimpressed with the song, they began rehearsing it with a rock band arrangement, changing the time signature from 2/4 time to a rockier 4/4 time configuration in the process. In an attempt to bolster the group's confidence in the song, Dickson invited Dylan himself to World Pacific to hear the band perform "Mr. Tambourine Man". Impressed by the group's rendition, Dylan enthusiastically commented, "Wow, man! You can dance to that!" His ringing endorsement erased any lingering doubts that the band had over the song's suitability.
