LONDON -- Andrew Lloyd Webber is looking forward to performing for the queen – once again.

Elizabeth ll's Diamond Jubilee celebrations continue Monday with a concert curated by singer-songwriter Gary Barlow. Lloyd Webber will join him on stage to perform their Jubilee song `Sing,' and he says that audience participation is paramount to their performance.

The composer admitted that although he no longer gets nervous when he meets the Queen, he realizes that "it is still a fantastic honor" to be asked to perform for her. The concert will be his first opportunity to join in Jubilee celebrations, as he has been busy in the lead-up with rehearsals.
