I screened a Spanish film at the festival, a true story about a schoolteacher who was a Beatles fanatic and who set out to meet with John Lennon when he heard that Lennon was in Almería to act in a movie ("How I Won The War" directed by Richard Lester). It's a great film, one of the very few from this year's festival that I truly want to watch.
To make a long story short, the schoolteacher did eventually meet with his idol. Apparently Lennon spent some of the time correcting the Beatles song lyrics the Spaniard had jotted down in his notebook. At the time, record sleeves didn't include song lyrics so fans would frequently get them wrong.
Every Beatles record released after this short Almería encounter included printed song lyrics.
