I thought it was a new trend. But have recently discovered posters for some shows at major British theatres in the 50s called 'Disc Doubles'.
One such poster boasts a bill that includes - Elvis, Doris Day, Ruby Murray, Eve Boswell, Frank Sinatra, Johnnie Ray, Mario Lanza, Frankie Laine, Liberace and Kay Starr !!
Now that would be some show ! But further down the poster it states ( in small print!) ....
'Your disc favourites impersonated by young stars that create a good impression!'
Impressions of famous stars by .... Beryl Bates, Des Symons, Ted Gilbert, Muriel Todd etc
Does anyone remember these shows ( 'Embassy' could have cashed in too with sound-a-like shows!)
