I always think about those Beatles singles that never existed and could have been great hits. Well, I've found this rare collection of vinyl singles made for jukeboxes in the 1990's, where we can find many alternate singles:

I see many interesting "unreal" singles in the list. I think some of them could have worked as actual singles in the 1960's. I like the following ones:
Norwegian Wood / If I Needed Someone
Lucy In The Sky With Diamonds / When I'm 64
Magical Mystery Tour / The Fool On The Hill
While My Guitar Gently Weeps / Blackbird
Here Comes The Sun / Octopus's Garden
