“Help! / I’m Down” was the tenth UK single from The Beatles.
From Wikipedia:
[…] The official release date for the “Help”/”I’m Down” single was 19 July 1965 on Capitol Records in the United States and 23 July on Parlophone in the United Kingdom. “I’m Down” was never released on an official Beatle studio album, and was only available in the US in mono as the B-side of the “Help!” single until the summer of 1976. That year, it appeared in stereo on Rock ‘n’ Roll Music, a compilation LP released in the US by Capitol featuring up tempo Beatles’ tracks. The first CD release was in 1988 on the compilation Past Masters, Volume One, where it appeared in true stereo. […]
Can’t say I liked ‘Ticket [To Ride]’ much. But this new one is — in my opinion — good. I hope I don’t sound big-headed. But I like it — it’s certainly the fastest record we’ve made and it’s very different. It’s a bit like the middle eight in “It Won’t Be Long”…
