Tunesmith,

The Beatles never appeared on Granada TV in 1962.

As Mark Lewisohn (pre-eminent Beatles reseacher) comments:

"As a direct result of Beatles fans' letters, producers from the Manchester based Granada Television had watched the group in action at Cambridge Hall in Southport on 26 July [1962] and again in the Cavern Club on 1 August. Impressed by what they had seen, a crew was dispatched this lunchtime [22 August] to film them in live performance for a programme entilted Know The North

The murky Cavern Club conditions were scarcely conducive to good filming, and the end result was largely umsatisfactory; the footage was shelved, deemed unfit for use, and was only exhumed for broadcast much later on, when the Beatles were famous. The first transmission was on Wednesday 6 November 1963, on Granda's evening magazine programme Scene At 6.30 "
