I did post this almost exactly three years ago on the occasion of George Martin's passing, but it was a bit out of place in that particular thread.
I thought I would resurrect the topic and give it a new life, because I love this song.
*****************
"Bad To Me" was an early Lennon / McCartney composition that was never recorded by The Beatles.
Attributed to John Lennon, the track was demoed by him in 1963, and shortly after covered by Billy J. Kramer & The Dakotas, an act who, like The Beatles, were managed by Brian Epstein, recorded for the Parlophone label, and were produced by George Martin at Abbey Road studios (Kramer was also a Liverpudlian - The Dakotas came from Manchester).
Coupled with another Lennon / McCartney original, "I Call Your Name" (that The Beatles would record in 1964), "Bad To Me" reached number 1 on the UK charts in the summer of 1963.
Here's Kramer & Dakotas' version, followed by Lennon's superb original demo :

Edited 21/04/21 in order to restore Lennon's YT link. - They keep removing this demo from YouTube. It's also available with overdubs, but this appears to be the only YT source for the undubbed recording as of today. It's followed by cropped footage of Kramer & The Dakotas performing the song live on Ed Sullivan' show (see below for a good version of this footage).
