Amy MacDonald in concert at the London Palladium

What on earth possessed Justin Bieber to be two hours late for his own concert? In one fell swoop the 19-year-old singer disappointed hundreds of young fans, infuriated their parents and set Twitter ablaze with criticism.

I reckon they should have gone to Amy MacDonald’s concert at the London Palladium the night before instead. The Glaswegian singer-songwriter (responsible for one of my all-time favourite tracks, Let’s Start a Band) arrived on time, took the packed audience by storm and left us all stunned by her talent.

I’d booked tickets months ago but when it came to it, my husband was on a work trip in Dubai and my daughter was in Paris. So I asked my 18-year-old son instead and even though he was dubious and his musical tastes are diametrically opposed to mine he sweetly agreed. His favourite music is “Trap,” which is apparently a mix of “southern hip-hop and Crunk” – and no, I’m still none the wiser.

But after a set lasting more than an hour, even my son agreed that Amy MacDonald and her band gave a storming performance. Now 25, she is a self-taught musician who started playing in Glasgow pubs ten years ago and has now sold more than five million albums. Her latest claim to fame came last week when she appeared on the BBC’s Top Gear programme. A self-confessed car fanatic who drives a Ferrari, she drove a Kia hatchback at top speed around a Surrey racetrack and was described by a clearly impressed Jeremy Clarkson as “one of the biggest petrolheads we’ve ever had on the show.”

But back to the Palladium. Amy MacDonald, a diminutive figure in a short black sparkly dress and sky-high boots, gave one of the most outstanding live performances I’ve ever seen. She’s halfway through a European tour and whether she was singing acoustic ballads or anthemic rock numbers held the audience in the palm of her hand.

She’s good at the chat too. Along the way we discovered that she recommended Irn-Bru as a hangover cure, that the song The Green and the Blue was inspired by her love for Glasgow and that, unlikely as it sounds, she and her band warm up to Higher and Higher, from the Ghostbusters movie.

The next day she was off home to Glasgow, ahead of a gig in Edinburgh tonight. If the audience was this rapturous in London, goodness knows what it will be like up there…
