Elaine wanted to share with you some back stage photographs from the star-studded Abba concert held at London’s Hyde Park on Sunday, 13 September 2009.

During this event Elaine & Siobhan McCarthy re-created a magical moment from the musical 'Chess'. Both singers who were in the original London stage musical cast of 'Chess' performed the duet 'I Know Him So Well' to an adoring crowd of onlookers at the 'Thank You For The Music: A Celebration Of The Music Of ABBA' concert.
