He first played drums with the Silver Beetles in May 1960, at the suggestion of manager Allan Williams, and later that month travelled to Scotland with John Lennon, Paul McCartney, George Harrison and Stuart Sutcliffe, when they acted as a backing band for singer Johnny Gentle.

During the tour, he was injured and lost his front teeth when the band's van, driven by Gentle, had a minor accident.

After they returned to Liverpool, Moore had already decided that he had 'had enough of Lennon'; when he did not appear for a gig one night, the rest of the band went round to his flat, and were told by his wife, Veronica (Vera) Hughes that he had gone back to his steady job at the bottle works.

[3] Speaking of his tenure in the group overall, Moore told a Portuguese magazine: I went to work for the Beatles through an advertisement I saw in a newspaper where Paul (McCartney) and George (Harrison) were looking for a drummer.

[5] Moore continued to work in Liverpool and died of a brain haemorrhage on 29 September 1981, seventeen days after fifty years old.
