Paul McCartney turned down appearing James Corden’s Carpool Karaoke numerous times.Back in 2018, the Beatles legend featured in Corden’s popular Late Late Show segment in a 23-minute skit through the streets of Liverpool, while singing some of the band’s most iconic hits.The video, which Corden said at the time was “quite possibly the best” episode of the show they had done, has since raked in 68million views.However, the talk show host has revealed that getting Macca into the passenger seat wasn’t a simple task.“He said, ‘I’m in, I’ll do it, I can’t wait,’” Corden recalled in a resurfaced 2021 interview with PaleyFest LA.“Then about a month later, the message came through to us that he’d cancelled, he didn’t want to do it. He’d got cold feet for some reason.
