I believe the striking thing about Macca and the rest is that, without being virtuosos,
they managed to use instruments in a way which brought out their inherent strengths (the instruments', I mean).
   Most would cite" Martha my dear"," Blackbird", harpsichord on "We can work it out",
"The end' for electric etc.
   In other words, Macca is a composer before he is an instrumentalist.
