Gavin and Stacey pivotal moment happened after Paul McCartney email
It was a pivotal moment in the Gavin & Stacey Christmas special, but needed a frantic email to Sir Paul McCartney to make it happen.
Oscar Hartland, 16, who played Neil the Baby, left the cast "bawling their eyes out" as he performed Blackbird by The Beatles.
It took place during the wedding ceremony of his on-screen dad Smithy, played by James Corden, with Hartland admitting he practiced for hours for the "make or break" moment.
But it almost didn't happen, with Corden requesting permission from McCartney after realising the show's budget did not cover permission to use it.
Corden thought it was "a beautiful song" and had lined it up for Hartland to sing, he said in new book When Gavin Met Stacey And Everything In Between.
"In terms of getting permission to use the song, the BBC have a licensing agreement which is great for UK transmissions of music," he said.
"But I think The Beatles sit outside of that, which we didn't know, and it's so expensive if you want to use one of their songs."
With the sitcom's budget not covering the cost of paying for the track, Corden wrote to McCartney asking permission to use it.
He said: "I wrote just telling him that I felt this was a pivotal moment in the show and that I would never request anything if I thought it was going to be in any way derogatory."
How did Sir Paul McCartney influence the Gavin & Stacey finale?
Corden added that he wasn't sure of the details but believes McCartney waived involvement which meant the programme could afford it.
"He said in his email that he was so touched and honoured, and he would love nothing more than this to happen, and they'd do everything in their power to make sure it could, and then, within 20 hours, it was done, and we had clearance to use the song," Corden said.
Hartland knew Corden had taken a risk on him and wanted it to be the best he could make it, he told Justine Jones on BBC Radio Wales.
"I just put so much into it and just tried to sing it with that raw emotion. That humanity level of emotion where you're like 'this is it'," he said.
Hartland said it was his "biggest task" in the episode, but he was in his element.
