08 March 2021 Share with: The Kings of Leon star and his bandmates were performing in Brixton in 2004 when the legendary Rolling Stones rocker appeared at the show and Caleb admits it was very "surreal". He said: "It was very distracting because we were playing the show and there were a few empty seats up top; and then before you know it, it's Mick sitting there and banging his arms on the balcony and dancing. We were all looking at each other like, 'Holy c***, this is very surreal.' I started shaking my hips a little more. Yep, I definitely did some dancing that I hadn't done before."
