Sydney the Platypus has come all the way from Oz to Glasgow in search of snow. His quest is quite a big adventure for Scottish Opera: following on from the success of BabyO, it's the company's first attempt at creating a show for the 3-5 age group and something of a learning curve for everyone.

If it was just Steven Rae and the Platypus puppet, we'd be star-struck. There's a bright and breezy warmth to the wee critter's resilient anthem "I'm just me" that reaches out to all ages in a way that the rest of Martin O'Connor's script doesn't. The patter, with its clever word-play, goes over the heads of most tots, and when - as is mostly the case - it's sung (by soprano Sarah Power and mezzo Sioned Gwen Davies), there's an odd opposition between the Glesca' patois and the operatic register of Rachel Drury's music.

The lovable Platypus, however, is a real charmer. He should come back, but maybe in a less ambitious project and more sing-along opportunities.
