Robin Gibb 'still fighting' lung infection

Bee Gees star Robin Gibb is still fighting a lung infection in hospital after being unable to attend the London premiere of his first classical work because he was too ill, his son has said.

The musician had been due to perform a new song, called Don't Cry Alone, at The Titanic Requiem concert.

The requiem was composed by both father and son and performed by the Royal Philharmonic Orchestra on Tuesday.

RJ Gibb said it was "heartbreaking" that his father could not make the performance.
