If you were in a pub and the band played a Beatles song, which one would you most like to hear? This may be moved to music but it's more of an emotional response I was after- something jolly and simple, a singalong, or Imagine or Yesterday sort of thing?!
The early stuff ('Love Me Do', 'All My Loving', etc) is both easy on the ear and easy to play. 'Here Comes the Sun' would be better for me but only if the band is actually good enough to render it faithfully (which most pub bands probably aren't!).
same as 237SJ.
When we were at school, our class used to love to sing along to "From me to you".
It started: Is there anything that you want? we'd shout out FISH AND CHIPS
Is there anything I can do? we'd shout PASS THE SALT ......... and so it went on.
