The youthful band of Preston Lodge High School in Prestonpans was only formed last year, but has already won the national championships, providing perfect preparation for the tough competition members will face at Glasgow Green on Saturday and Sunday.
The event comes hot on the heels of the band's success in winning the Novice Juvenile category at the British Pipe Band Championships at Bathgate, West Lothian.
Then it beat off 26 youth bands from all over Scotland in a result which was hailed as stunning by the Pipe Major Lee Moore. The group, who have been working hard over the winter, are expected to bring strong support through from East Lothian.
The band is due to compete in the Novice Juvenile section, where members will face tough competition from 27 other schools, including one from Canada, the Robert Malcolm Memorial Pipe Band, part of the world-renowned Simon Fraser Pipe Band, from Burnaby, British Columbia.
The Canadians will be hoping to better their third in the category in 2012, their last appearance at the "worlds". They have already performed at the North Berwick and Perth Highland Games, Blair Castle and in Pitlochry since coming over to Scotland last week.
Meanwhile, more than 200 events are taking place this week at Piping Live! Glasgow International Piping Festival. Now in its 11th year, Piping Live! will bring 50,000 spectators from such countries as France, Spain, USA, Australia, and Macedonia to Glasgow this week, with more than 150 events taking place across the city over the next seven days.
The event is being held for the first time in Candleriggs in the Merchant City. The world's biggest piping festival has brought in almost £20 million to the city over the years.
