Thought it was worth mentioning some of the members of the Quarrymen here, as I saw them live recently.
There are seven members still living including McCartney. The band reformed back in the 90s and do occasional gigs. I saw them last month and there are only two original members performing now (banjo player Rod Davis, b. 1942, and drummer Colin Hanton, b. 1938). They mentioned on stage that John Duff Lowe (piano, b. 1942) and Len Garry (tea-chest bass, b. 1942) are too unwell to perform now. Lowe hasn't performed with the band since 2017, but Garry's retirement is new. The two other remaining members are Bill Smith (1940) and Nigel Walley (1941), neither of whom have ever joined the reformed band. Of those six, Hanton and Lowe are probably the most notable as they appeared on the Quarrymen's "That'll Be the Day" and "In Spite of All the Danger", recorded straight-to-disc at Phillips' Sound Recording Services in 1958. These are the first studio recordings of Lennon, McCartney and Harrison and appear on the Beatles' Anthology 1.
