Intimate solo cabaret featuring Deborah Brennan as storyteller and songstress. Enchanting show based on an unlikely true story of a chance encounter with a stranger that sets in motion life-changing events. The Hummingbird Effect is the name given to the idea that one moment of inspiration leads to another which leads to another. This idea has formed the basis for Deborah Brennans newest show. This beautifully put-together show is absolutely what cabaret should be ***** (GlamAdelaide.com.au). Brennans personal engagement with the music is the fuel that powers the show and lights it up **** (TheEdinburghReporter.co.uk).
