Maltese tenor Joseph Calleja is currently having his first rehearsal with the national orchestra for his concert with Michael Bolton on Sunday.
Gillian Zammit, Ivan Grech, Chiara Siracusa and the 270-strong choir which was formed purposely for the occasion are also rehearsing.
The rehearsals are being carried out under the direction of Paul Bateman at the Mediterranean Conference Centre. There will be other rehearsals tomorrow and on Saturday.
The concert, organised by Nng Promotions, will be followed with another by Laura Pausini on Tuesday. Both are being held at the Luxol Grounds.
