 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 were initially unimpressed with the song , they began rehearsing it with a rock band arrangement , changing the time signature from 2 / 4 to a rockier 4 / 4 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 ! " , and his ringing endorsement erased any lingering doubts that the band had over the song 's suitability .
