The instrumental track was loosely based on the Christmas carol ‘Silent Night’, albeit arranged to sound like it belongs in a Western.
The US pressing of Wonderwall Music erroneously listed the title as ‘Cowboy Museum’.
Excerpts from ‘Cowboy Music’, ‘Ski-ing’, and ‘Wonderwall To Be Here’ appeared in the soundtrack of Apple, a promotional film production produced by Tony Bramwell in 1968.
