I'd earlier mentioned a British television series on conducting with various "personalities" competing. Here a report from The Scotsman.
The author notes:
In each episode of the six-week series, the eight celebrities – drum and bass star Goldie, actress Jane Asher, comedian Sue Perkins, actor Bradley Walsh, newsreader Katie Derham, TV presenter Peter Snow, actor David Soul and pop musician Alex James – will have to conduct a full orchestra in front of a live studio audience. Each week, one will be voted off by an expert judging panel. The victor will win the chance to conduct the BBC Concert Orchestra in front of an audience of 30,000, live on BBC2 at the Proms in the Park, as part of the Last Night of the Proms celebrations on 13 September.
He further notes about Goldie:
I watch, fascinated, as Goldie climbs on to the podium at St Cyprian's. A giant, shaven-headed fellow with an imperious demeanour, he is dressed in a yellow T-shirt, tracksuit bottoms and trainers. Gold teeth glint from his mouth. Yet the moment he launches into conducting, I – and the entire orchestra – are spellbound. Eschewing a baton, Goldie communicates the beat through a mesmerising rhythmic dance on the podium. A great slab of a man possessed of a raw physicality, he simply dominates proceedings with his sheer charisma. As he rallies the musicians to a rousing climax in the Brahms and the cymbals and kettledrums crash and pound, I am enveloped by what Phil Spector, in rather different circumstances, called a wall of sound. I'm even more taken aback when the PR leans over and whispers in my ear: "He doesn't read music, you know. He's doing it all on instinct."
I'm glad you don't need any training to conduct Brahms!
