RockGeek Fact of the Day #1109

On most CD pressings of "Dark Side of the Moon", a barely-audible orchestral version of The Beatles' "Ticket to Ride" is audible after "Eclipse", playing very faintly over the heartbeats that close the album. It is unknown why this was included, but it may have been the consequence of a mastering error. The bootleg recording A Tree Full of Secrets includes an amplified, re-processed version of this oddity, which allows it to be heard clearly.
