As Coldplay’s huge 10-night residency at London’s Wembley Stadium rolls on, the surprises keep on coming. For Tuesday’s night three (Aug. 26) of the record-breaking run, the band were joined on stage by Simon Pegg for a performance of “A Sky Full Of Stars,” for which the actor played the tambourine throughout. 

Following the appearance, Pegg shared an image of his instrument on Instagram Stories, captioning it: “Rejoined the band.” Watch footage of the moment here.

Pegg, who has starred in blockbuster films such as Mission Impossible and Shaun Of The Dead, is a longtime friend of Coldplay. He has previously dubbed himself an “honorary member” of the London-formed band, having appeared on stage with them numerous times over the years, including introducing the four-piece at their intimate Shepherd’s Bush Empire gig in 2021.

The Avicii-produced “A Sky Full Of Stars” came towards the end of Coldplay’s 23 track-long set, which encompasses highlights from across their career as well as material from 2024 LP Moon Music. Upon release, the chart-topping record saw the band tying legendary acts ABBA, Michael Jackson, and Queen, each boasting 10 No. 1 albums on the U.K. Official Albums Chart.

Moon Music also hit the summit on the Billboard 200, marking Coldplay’s first US No. 1 record since Ghost Stories, which landed in 2014. They have since supported the release with worldwide dates for their Music Of The Spheres tour, which has also taken them to Europe, Asia and North and South America, Australia and New Zealand. 

Coldplay will return to Wembley Stadium tonight (Aug. 27) ahead of further concerts at the venue on Aug. 30, 31, Sept. 3, 4, 7 and 8. The run already has seen them treat fans with a surprise rendition of 2002 track “Politik,” while frontman Chris Martin helped a couple with a proposal mid-set last week (Aug. 22).
