Paul McCartney has announced his first new album in six years, described as a "collection of revealing glimpses" into "never-before shared" memories.

The Boys Of Dungeon Lane was inspired by his childhood in post-war Liverpool, and named after a road in Speke that leads to the Mersey shore, where the young McCartney would spend afternoons bird-watching.

The first single, Days We Left Behind, premiered on BBC Radio Merseyside, and finds the singer in a wistful, nostalgic mood.

Over a simple acoustic backing, he reminisces about "smokey bars and cheap guitars", observing that while Liverpool is always changing, "nothing can erase the days we left behind".

Singing in a delicate falsetto, his voice conveys some of the frailty of age, lending the song a powerful emotional punch.
