Another couple of rarities from Beatles producer George Martin. He collaborated with Maddalena Fagandini on these two songs, Time Beat and Waltz in Orbit, the A & B sides of a single released on the Parlophone label. They were released under the pseudonym “Ray Cathode.” Fagandini, who was a part of the BBC Radiophonic Workshop, worked alongside Delia Derbyshire on Doctor Who sound effects. This would have been recorded mere weeks before Martin met the Beatles in 1962. (Audio for Time Beat is here)
 
Bonus clip: The Beatles appear on Doctor Who in 1965. Imagine jumping into a time machine and getting to see the Beatles! Sadly this scene only appears on British Region 2 DVDs:
