Sir Paul McCartney has suggested late Beatles bandmate George Harrison helped him write a song for his latest album from beyond the grave.
Sir Paul wrote Waiting For Your Friends To Go for his new album
Sir Paul said he wrote Waiting For Your Friends To Go with help from Harrison, who died in 2001.
"I just got this feeling, this is George," he told Tom Robinson on BBC digital station 6 Music. "I was like George - writing one of his songs."
"It just wrote itself very easily because it wasn't even me writing it."
Sir Paul said he was remained unsure about the meaning of the song's lyrics.
"I thought, OK, the 'waiting on the other side' is also a little bit loaded, it can be crossing the river Jordan or whatever, that sort of thing. There's a little bit of double meaning there," he said.

"It was funny, particularly the second verse: 'I've been sliding down a slippy slope, I've been climbing up a slowly burning rope.' I just thought - it's a George song."
Sir Paul said the song was one of his favourites on his new album Chaos and Creation In The Back Yard, which is due out in September.
The interview will be broadcast on 14 September.
