And then we've had subsequently just lots of great gigs there, just amazing ones. It is good to spread 6 Music's message far and wide.''
And Public Service Broadcasting added: ''We're absolutely delighted to be part of The Biggest Weekend in Belfast - it's an honour to be part of an event like this and a special honour to be asked by the BBC to compose some new music specifically about the Titanic and perform it in front of Titanic Belfast. We really can't wait and hope to see as many of you as possible in May.''

Wherever you are in the country, you will be part of the biggest music event, with the widest selection of musical genres, the BBC has ever put on.''
