Although their act is only around three years old, Katzenjammer have literally been around the world - and it's easy to see why they are in such demand.
Such is their originality, it's difficult to do justice to their talent in words. Steven Worbey and Kevin Farrell are both classically trained pianists who could give a virtuoso performance in their own right, but together they add a highly comic display of ability that's simply breathtaking to watch.
Both guys play the same piano at the same time - their hands dancing in between each other over the keyboard. They make it seem effortless, but a close up of the keyboard is projected on a large screen above them so you can fully appreciate just how talented they are.
The programme tonight is an eclectic mix of classical, music hall, modern and original compositions - with some styles played at the same time; for instance imagine Moonlight Sonata with the melody of How Much Is That Doggie In The Window over it. It's wickedly clever stuff, but not at all high-brow. Steven and Kevin tie the show together with camp banter that feels improvisational. You can't be quite sure whether you're going to see the same show twice.
Predictably, the audience beg for more when the time is up, and the boys happily oblige with a sing-a-long version of Pomp & Circumstance by Elgar which not only gives them a final opportunity to show off their skill at the keyboard, but also has the whole theatre singing Land Of Hope And Glory. Not a bad achievement in Scotland.
