Calder's grounding in the industry began in the early 1960s at Decca Records under the direction of Edward Lewis.
In 1962 Calder was hired by Brian Epstein to promote The Beatles single "Love Me Do",[REF] which he did successfully by sending free copies to the top fifty Mecca Ballrooms and also the opposition Top Rank ballrooms, in order to persuade the local independent record shops to order the record.
