Theodor Wiesengrund Adorno, born 1903, died 1969.
He was a Neo-Marxist philosopher, Holocaust survivor, composer and, apparently, fifth Beatle.
Olavo Carvalho, Brazilian president Jair Bolsonaro’s political guru, said: "The Beatles were semi-literate in music, they barely knew how to play the guitar. Who composed their songs was Theodor Adorno."
If you play "I want to hold your hand" and "She Loves you" backwards, you hear Adorno saying: ‘Advancing bourgeois society liquidates memory, time, recollection as irrational leftovers of the past'. The Beatles didn't like that, so they released a proper German version " Komm Gib Mir Deine Hand" and "Sie Liebt Dich"
