In March, Foo Fighters drummer Taylor Hawkins died suddenly at the age of 50, and the surviving band members immediately cancelled all of their plans. Last week, Hawkins’ Foo Fighters bandmates announced plans for a couple of huge concerts that would pay tribute to Hawkins — one at Wembley Arena in London and one at the Kia Forum in Los Angeles. At the time, the band didn’t announce any of the all-star guests who would appear at the shows. Today, though, they’ve said which stars will perform at the London show, and there are a lot of them.
