apart from very minor changes (e.g. the ascending guitar chords before the middle section) is very close to the song that has always been regarded as one of the keystones of the 'BGTY' era....despite the fact that it was created by (drum roll.....) the MJ/DL/TW/MA line up during those odd few months previously.
Apologies for the awful name-dropping here, but I was chatting with Phil about Bananas (as you do) after the New Roscoe show. As he recalls it, the main riff was already in place, and Micky played it incessantly during the early days of the then new band's line-up. Will wrote the "I like to eat bananas" words, Phil contributed the "Plant the seed into the ground" section including the lyrics, and worked on adding the arrangement for the instrumental middle section.
