Haha indeed! It exists. Bungalow Bob probably won't like it - and I wouldn't blame him; it's definitely not a great song, just a bit of a goof - but note the obvious ripoff/parody of two Beatles classics within. (This one's from the album previous to Let It Be, incidentally.)
As for borrowed Beatles titles: Badfinger did "Love Me Do" (way better song than the earlier one), and Motorhead did "I'm A Loser", and the Velvet Underground did "What Goes On" (also superior to the Beatles) and Wire did yet another "I Should Have Known Better", ...
