James Corden and Paul McCartney have teamed up for a Comic Relief Smithy sketch.
Corden will reprise his popular Gavin & Stacey character for the TV fundraiser and will be joined by the Beatles legend.
"It blows my mind to think we were filming with Sir Paul McCartney," Corden told the Radio Times. "He was open and warm, and very respectful to all the people involved. He was funny too, and he didn't take himself too seriously, because that's what you're asking the stars to do in these sketches.
"And that can be the biggest hurdle to get over, asking them to put it before themselves and remember the big picture. He was really aware of that."
McCartney added: "I love the shorts that James does for Comic Relief, so I really was just keeping fingers and legs crossed that it would work. In the end my fear subsided and I enjoyed it very much."
Comic Relief: Funny For Money begins on March 18 at 7pm on BBC One.Last Updated: 03/09/11 13:59
