It would me, Queen + Adam Lambert is so much more than just his vocals, he's been doing it for over a decade now and really is part of the family. Not knocking Sam, I thought he was brilliant and I don't think it's the last we'll see of them together, but Adam Lambert isn't going anywhere...
Sam Ryder impressed me when singing with Queen on Somebody to Love, you could see Brian passing judgement on the high note near the end, looks like he approved.
Although I've got a couple of earlier F1 memories, the most vivid is Murray having to stop because he had a lump in his throat when Damon won his title in this.
