Marco's Comments:
Biographies of some artist of American Vaudeville. It's a collection of interviews to a number of vaudevillians of the last age of vaudeville (1920s-30s): most of the artists are comedians, dancers or singers. Only one "magical" act is contained, Alan Corelli, who did a sort of "strong" act, and the ventriloquist Edgar Bergen.
The book is very interesting for the description of the life behind scenes at vaudeville.
