The One Show's Roman Kemp brands dad Martin an 'idiot' after owning up to big 'mistake'

July 1985 saw the biggest rock concert in history, as some of the hottest stars of the era took to the stage in London and Philadelphia to raise money for victims of famine in Ethiopia.

One of the acts that appeared in the Live Aid lineup at Wembley Stadium was Spandau Ballet. Now BBC's The One Show star Roman Kemp, son of Spandau bassist Martin Kemp, has accused his dad of being an “idiot” after making a major faux-pas during the star-studded concert.

Spandau were sixth on a bill that included most of the biggest bands of the era. They chose to play two of their recent hits, Only When You Leave and True, along with Virgin – a cut from their then-upcoming album Through The Barricades. But the latter didn't go down well.

Speaking on You About?, one of his four regular podcasts, Roman told pal Tom Grennan that his dad’s mistakes had inspired a solid piece of advice: “The number one thing that my dad always has the most is, ’Enjoy the moment.’

“Because the thing is,” Roman added, “if you're too focused on something else, you could do what my dad did, which was play a new song at Live Aid.”

"They played a new song that no one knew really," he added, before branding the band "idiots" for making the wrong decision.

30-year-old Tom, currently riding high at No.1 in the UK with his fourth album, expressed his surprise that Martin had even played at Live Aid.

Earlier this year, Martin made a confession to Roman all about the band’s embarrassing error: "Tony goes up to the mic – with two billion people watching – and goes, 'Here's a new one.'

"And two billion people around the world go 'Oh b******s.' You know when you go to see a band and they play a new song off the latest album? You don't want to know.”

"It was the worst mistake of our lives," Martin told Roman. "It was terrible, because Virgin was a track that we'd rehearsed. It was going to be on a new album coming out..."

Spandau were, along with Adam Ant, one of the only acts to perform new material that day. They made that mistake, Martin said, "because our egos were bigger than everyone else's".

He said that older brother Gary chose the song, although, in another interview, Gary laid the blame on band manager Steve Dagger.

Despite his disappointment in his own band's performance, Martin recalled that sunny Saturday in July 1985 as one of the highlights of his musical career.

Standing with the rest of Spandau as they watched openers Status Quo from the side of the stage was "probably the happiest that I ever knew my band," Martin said.

He continued: "We were standing on the side of the stage watching them, and it was absolutely beautiful. It's my favourite memory of being in the band."

Another treasured moment from that day for Martin was a brief rest at home with his wife Shirlie, who had just returned from a lengthy tour with her band, Wham!, before heading back to Wembley for the climax of the show.
