YESTERDAY
“Yesterday”, written entirely (or almost entirely– read on) by Paul McCartney, is either the most, or second most, recorded song of all-time. (Guinness World Records claimed it was the most, but this has been contested with others claiming George Gershwin’s 1935 “Summertime” is the true owner of that mantle.) Whatever the case, to date, at least 4,000 different versions of the classic “Beatles” tune have been recorded by artists as diverse as Frank Sinatra, Elvis Presley, Liberace, Tammy Wynette, Daffy Duck (!), The Mamas and the Papas, Marvin Gaye, Ray Charles and Placido Domingo.
