The Beatles recorded two shows for the radio series Side By Side, to be broadcast on the BBC Light Programme service.
The shows were taped at the BBC's Piccadilly Studios in London, and the presenter was John Dunn.
The format of the show was that each week the house band, The Karl Denver Trio, invited a guest act to perform. Both acts normally performed the theme tune together.
Including the rehearsals, the radio sessions took place from 2.30-5.30pm and 6.30-10.30pm. The first show was broadcast from 5pm on 22 April 1963, and the second one at the same time on 13 May.
