The Forgetting Sarah Marshall star thrilled the 80,000-strong crowd - as well as well as millions of TV viewers around the world - with his tribute to Willy Wonka & the Chocolate Factory and the Beatles during his performance at the Olympic Stadium in London on Sunday (12Aug12) to mark the end of the 2012 Games.
However, Brand was nursing a bad back ahead of the ceremony - and as he worked out his routine at rehearsals last week (begs06Aug12) he sought advice from sportsman Beckham.
He tells Britain's The Sun, "I was speaking to David Beckham, who was there with his lovely wife Victoria, and I was asking him about pain relief for a bad back.
"I've got this pain in my lower back and I asked him if he had one of those injections for the pain when he was playing. He said all I needed was a massage, but he wasn't exactly offering."
