Singer Sam Smith cheekily reassured the audience at the BBC Proms that they wouldn't be seeing any of their usual on-stage antics. The pop star was welcomed to the historic Royal Albert Hall for a night celebrating their career, with the concert being broadcast on BBC Two on Saturday evening (August 24).

Dressed in a smart double-breasted black suit, they joked: "Before I introduce you to some incredibly important people, I just wanna say to everyone here that don't worry - I'm not going to get my bum out! The audience responded with laughter, after which Smith added: "The clothes are staying on, OK? The clothes are staying on.

"This is going to be an appropriate show - even I know there's a time and a place."
