The joke is that when someone is taking requests for songs everyone shouts “PLAY WONDERWALL!” or that a new amateur busker will confidently walk up to the mic and say “Here’s Wonderwall”. It’s a great joke, but it only works because people are so familiar with the song. It’s universal appeal and its simplicity only add towards how valuable this song is to modern music history.
A fine point in British Rock music for sure.
Not only do you get this classic track, Creation are nice enough to give us three additional tracks including the wonderful The Masterplan.
