Geoffrey Mark has been called a “walking encyclopedia of show business history.” Honestly, you can’t stump the guy! A singer/stand-up comedian in nightclubs and cabarets and an Off-Broadway veteran, Geoffrey has hosted radio series, written comedy and now writes and produces documentaries and reality shows for cable television. Geoffrey also has written three best-selling books, devoted to Lucille Ball, Ella Fitzgerald and Ethel Merman. Special thanks to Gary Alan for recommending Geoffrey to us!
