ABBA have shared a promo for their new holiday merchandise with actor Ian McKellen. 

The star appears alongside Björn Ulvaeus in the footage, which sees the pair knitting garments in support of the band’s festive single Little Things. 

The silent video ends with a clip from the song and the message: “Merry Christmas from ABBA and Ian McKellen”. 

The jumpers are available to order from the official ABBA online store. 

Due December 3, Björn says of the track: “Benny (Andersson, co-writer) tells me he didn’t think of it as a Christmas song, but I, the minute I heard it, I said it cannot be anything else.

“It is early, early Christmas morning. The stockings are hanging right there and then this couple wakes up.”

He adds in an Apple Music track-by-track: “This could be played for Christmases to come. And that would be great, because we want to own Christmas and New Year’s Eve, like with [1980’s] Happy New Year.”

Little Things will be available digitally and as a limited-edition CD single.

In a review of the album, Retro Pop called ‘Voyage’ “a fitting closing chapter in the tale of Sweden’s best-loved musical export”.

‘Voyage’ is available on CD, vinyl and cassette.
