Fourteen musicians and 12 opera singers combined their talents for an impromptu performance which lasted almost an hour.
Crowds turned up in their thousands to enjoy the music, which included classical pieces, opera arias and musical numbers.
Shoppers and visitors delved deep into their pockets, and raised more than £2,200. Congratulations to all those involved!
