And the twin guitars in this one from 1966! Stunning!
Said to be Harrison & McCartney, but I'm inclined to think it's McCartney double tracked. You just don't get two completely different guitar styles meshing so perfectly. Around that time, Harrison's playing was exemplified by 'Act naturally', whereas McCartney's was perfectly shown on 'Taxman' (yes folks, all the lead guitar work on that track is McCartney).
