I’m thinking Joe Sinnott probably had Bing Crosby’s Hey Jude/Hey Bing! album in his record collection. 65-year-old Bing covered two Apple label singles from the fall of ’68.
On December 11, 1961, ABC-TV in America broadcast a TV special that Bing had produced in England, in which he performed this humorous rendition of ‘The Sheik of Araby’.
A few weeks later, on January 1, 1962, The Beatles, with Pete Best on drums, recorded their own humorous take of ‘The Sheik of Araby’ at their Decca Records audition.
