As far as I am aware music for the event went to the level of "The Saturdays" and that was it. 
It would have been very fitting to have heard Mark singing "Remembrance Day" once more at Trafalgar Square on Thursday, or even on a TV programme, such as "The Andrew Marr Show" this Sunday morning, which always ends with some music - this morning it was a cellist. Mark would have been a better choice on this particular Sunday, but maybe he would have declined anyway at the moment.
