Elaine Paige's 50th anniversary album 'The Ultimate Collection' out 12 May 2014: smarturl.it/ela...
Elaine Paige and Tommy Korberg sing 'Mountain Duet' live in Stockholm, 1984.This was part of a televised concert promoting the album 'Chess' with the original LP's cast members.
Other videos are already on UA-cam of 'Pity the Child' and 'Nobody's Side'.
Benny and Bjorn of ABBA are in the orchestra and play different roles, such as the piano, the accordion and the typewriters in 'Embassy Lament'. Barbara Dickson apparently took ill during the concert, and didn't sing her role in 'Endgame,' when Karin Glenmark (Anders Glenmark (the Arbiter's) wife), took over and stole the show.
