The Beatles were never regulars at either Anfield or Goodison Park - so it really depends on which titbit of folklore you choose to swallow.
Donald Philips is among many who think that the Sergeant Pepper cover is the killer giveaway. Standing just on Marlene Dietrich's shoulder grinning madly is Albert Stubbins, the red-haired Liverpool centre forward - and the only player to make the many-faced cover.
While there are those who claim, rather mean-spiritedly, that Stubbins only made the cover because John Lennon liked his name, many more are determined to prove that the Beatles worshiped at the Kop when not hopping across the continents for a visit to the Maharishi.
Karl Coppack comes up with Paul McCartney trying to get the 1977 Liverpool v Man United FA Cup final on the radio while on his boat in the Caribbean, while the words clutching at straws come to mind for both Stephen Pepper - who recalls the Beatles wearing a huge red-and-white scarf in a skiing scene of Help! - and Ian Gresham, who remembers snaps from 1968's Mad Day Out photo session of McCartney wearing a red-and-white rosette.
A number of you with a worrying knowledge of Beatles lyrics also point out that Matt Busby - an ex-Liverpool player - gets a namecheck on Dig It.
But there are equally tenuous claims for a link between McCartney and Everton. Paul has been known to mention that his uncles used to support the Toffees - and that every now and then he would tarry along with them.
And then there was the rumour that warmed Everton hearts a couple of years back that McCartney was about to invest a lot of money with the club. They're still waiting for that investment.
The real answer seems to be that the Beatles did not have any great love of football - unusual in four lads from a footballing city, as Karl Naden points out, but not impossible. Indeed, the only positive sighting of a Beatle at a sporting event comes from Iain Saunders, who sat behind McCartney at a New York Yankees baseball game.
Finally George Harrision's reply to those impertinent enough to ask which club he supported was the obtuse: "There are three teams in Liverpool and I prefer the other one." Which leaves us very much where we started.
