My Sweet Lord
Embracing Hindu spirituality, George became a plain clothes devotee of the Hare Krishna Movement - a "closet Krishna", as he called himself.
Harrison would go on to write the song 'My Sweet Lord' - from his acclaimed 1970 solo LP 'All Things Must Pass' - with the lyrics intended in praise of the Hindu god Krishna.
Following the recording of the track, his producer Phil Spector immediately predicted it was "a hit record" and he was proven right.
'My Sweet Lord' topped the charts in both the US and UK, the first track by a former Beatle to do so.
It returned to the top in Britain in 2002 after being re-released following George's death.
