Donovan's song 'Mellow Yellow' is about a vibrator'
In an interview with the June 18, 2011, edition of the NME, Donovan was asked what the song was actually about? He replied: “Quite a few things. Being mellow, laid-back, chilled out. ‘They call me Mellow Yellow, I’m the guy who can calm you down.’
'Lennon and I used to look in the back of newspapers and pull out funny things and they’d end up in songs. So it’s about being cool, laid-back, and also the electrical bananas that were appearing on the scene – which were ladies vibrators.'
