OK, here goes Grillo. I could look it up in McDonald's book - but here's my go off the top of my head:
I Don't Want To Spoil... John lead vocal, single track. Paul harmony.
Little Child. Would need to listen again to be sure. I think John, Paul and George are all on this one, John and Paul singing lead together.
Things We Said Today. Double tracked Paul. No other voices appear - just like Can't Buy Me Love.
Hold Me Tight. Paul lead, John and George on backing. Oh, there's a point on this one where Paul sings "right now" and John "right so", about a minute in I think......
