Live from Belfast’s Waterfront Hall, John Humphrys - AKA him off Mastermind - hosts this commemorative event to mark the centenary of the sinking of RMS Titanic. A blend of music and documentary, the show features special performances from Bryan Ferry, Joss Stone, Ni-cola Benedetti, Alfie Boe, Charlie Siem, Maverick Sabre and the Ulster Orchestra. The per-formances wrap around a documentary which tells the story of the ill-fated ship, those who built her, the people who sailed on her and the enduring legacy of the tragedy. If you missed The Sinking of the Concordia: Caught on Camera, Channel 4 are repeating it at 8.15pm to-night. It's well worth your time.
