CLASSICAL crossover superstar Andre Rieu has canceled his Glasgow concert.

Andre and his 60 piece Johann Strauss Orchestra should have played the Hydro on December 23.

But the violinist and conductor has released a statement saying a musician, who has been with the Orchestra for more than 20 years, suffered a severe heart attack on Saturday.

His condition is currently critical and so concerts in Glasgow, London, Birmingham and Manchester have been postponed.

A statement from Andre said the Orchestra is like "a family" and to continue the tour would be "impossible".

The statement reads: “It is with deep regret that I have decided to also postpone my concerts in London, Birmingham, Manchester and Glasgow.

"This should have been the most wonderful time of the year, and we were looking forward to bringing joy and happiness to all of you, our beloved audience.

"But many of my orchestra members have been with me for more than 25 years. We are a family.

"We are deeply saddened by this tragic event and it is impossible for us to continue our tour as planned.

"Thank you all so much for your understanding in this difficult moment. Our hearts and thoughts are now with our colleague and his family."

Bosses at the Hydro said new rescheduled dates will be announced as soon as they become available.
