POET and playwright Roger McGough is loaning a pair of Paul McCartney’s trousers to the World Museum Liverpool.

The pair of blue mohair pants were given to him by the former Beatle’s brother Mike when they were both members of 60s group The Scaffold.

They will be displayed as part of the Beat Goes On Exhibition alongside a poem penned by the Liverpool Poet entitled “To Macca’s Trousers”.

McGough said: “Paul used to give Mike some of his old cast-offs and the trousers were too short for Mike so he gave them to me.

“I never wore them, forgot I had them and then I realised ‘oh I’ve got a pair of Paul McCartney’s trousers’.

“Then, as the trousers unfolded, so did the story.”

Also in his possession was a second pair, this time in green tweed, which he gave to Mike Hart of band The Roadrunners.

McGough added: “I didn’t want to put them on eBay, just because of knowing the family, it would be a tacky thing to do.

“Having written the poem about having them framed and hung I thought ‘there’s an idea’, And it becomes like art work in a way.

“They were part of a blue mohair suit and they’ve got quite a sweaty waistband. They’ve obviously been worn a bit.”

To Macca’s Trousers will be published in a new collection of McGough’s poetry, At An Awkward Age, released next month.

It includes a series of addresses to objects including contact lenses and Meccano.
