Here’s an acoustic version with Rod on vocals in case you still have doubts.

I always thought the Monkees theme they said. “Went to Betsy singing, to put anybody down.” I didn’t know who Betsy was but there seemed to be a lot of popular songs where they threw in some random girls name.
Like “Just Give Me Some Calasandra” (Some kind of sign girl).
Those tinny transistor radios weren’t known for their high fidelity sound.
Lastly. On John Lennon’s version of Stand By Me, I SWEAR he sings, “The Moon is the only flying pussy.” I’ve told several people about that and now they say they can’t hear it any other way.
Thanks for the link, that was an awesome live performance of the "Maggie May" song.
