The album Abbey Road was nearly called "Everest".
(This would have meant that one of the pop world's most iconic photos was nearly never taken, but the idea of schlepping up Everest for a photo shoot was abandoned, and on 8th August, 1969 the Fab Four walked out of No 3 Abbey Road, and whilst a policeman held up the traffic on Abbey Road, the photographer Iain Macmillan took photos as the band walked back and forth.
Since then quite a few people have reproduced that moment, but with no friendly policemen around, they are taking their lives in their hands.)
