Youngsters from St Aloysius' College Junior School saw the popular venue transformed into a seaside setting in preparation for the Underwater Party, provided by Glasgow Unesco City of Music.

Families, who are encouraged to dress up seaside-style, will be treated to a disco, various musical events and performances, a treasure hunt, face painting and crafts.

There will also be a Deep Sea Tank with flying fish, sharks and a Dark Room full of sea fog and mysterious sounds.

Svend Brown, director of GUCoM, said: "The Underwater Party promises to be a fantastic day out. There's something for everyone from babies to Mums and Dads.

"We're throwing open the doors of the Glasgow Royal Concert Hall and inviting families to join us for a day of musical fun - the whole venue will be buzzing with entertainment and activities, which are all completely free, and families can drop in at any point during the day."

GUCoM's Underwater Party is free to attend.

Children's Classic Concerts with Owen and Olly and Dr Octopus and the Wheels of Steel are free but ticketed, and booking in advance is strongly advised as capacity is limited.
