U2 kicked off their residency at the MSG Sphere in Las Vegas by dedicating one of their tracks to drummer Larry Mullen Jr, who is not taking part in the shows due to various injuries.The Irish rock icons launched their long-awaited residency at the new MSG Sphere in Nevada last week, and used the opening show to pay tribute to the absent member.Bono, The Edge, Adam Clayton and stand-in drummer Bram Van Den Berg all made a nod towards Mullen Jr during the set, dedicating their 1988 track ‘All I Want Is You’ to him. The drummer is not taking part in their 25-show residency at the £2.3billion venue due to injuries sustained to his elbows, knees and neck.He previously confirmed that the injuries are all drumming-related, and said that he would “like to take some time… to get myself healed”, rather than persevere with the Las Vegas shows.
