I don't know. It's always hailed as a monumental breakthrough, some kind of maturing thing, but did the world really need rock and roll bands singing ballads set to strings? I for one hate the fact that the greatest R'n'R band in the world could well be remembered for this granny pleaser, and cue a hundred otherwise good hard rocking bands hitting the charts with totally out of character power ballads.

I think Yesterday is a bit of Pauls Frankenstein, and the monsters gonna get him in the end.

Quoted from Jim_Colyer

I prefer Daytripper over Yesterday.  Daytripper was on the flip side if I recall.  Yesterday is okay but overrated.  I generally pick John over Paul.

Daytripper was on the single with We Can Work It out. Personally I love yesterday. One of my favourite Beatles songs.
