Side by Side - the Callaway Sisters. On You tube. 4****. William Russell

After a 14 month separation the sisters - celebrated canaries on and off Broadway - meet up for a joyous reunion doing what they do best - singing songs. Liz flew from New York to her sister Ann's house in Tucson to perform together songs from the shows they have appeared in on Broadway - both have been Tony nominated - and in Cabaret over a long careers. Lizmade her Broadwat debut in Sondheim's Marrily We Roll Along, starred in theoriginal Broadway production of Miss Saigon and played Grizabella in Cats for five years. Ann is a cabaret star and composer with over 50 CDs to her name. You can watch on demand until 31 May. Expect to hear lots of Sondheim, songs about love, songs about sisterhood and yes they will sing the one about sisters being devoted sisters. This is American show business glamour and sparkle as they vie with one another, recall memories of shows and performances and do what they do best - sing.
