When Tony-nominated sisters Ann Hampton Callaway and Liz Callaway combine musical forces, they put the revelry into rivalry in this award winning show of great songs and witty banter. SIBLING REVELRY was first presented at New York’s Rainbow and Stars, garnered raves at The Donmar Warehouse in London, and continues to sell out halls across the country. The best selling CD on DRG Records, remains one of the classic cabaret must-haves.
