I thought I had every Beatles track. But I don't have this. And none of the usual vendors seem to have it.
I did find a very good version on Youtube which sounds like it's the original but there are no harmonies. Probably the vocals were all mixed onto one track and so the harmonies were removed at the same time as the lead vocal.

Can anyone help? Or do I have to fire up Audacity and add my own squeaky harmonies?
