Greg Morrison is a Canadian composer and writer best known for his work on the Tony Award-winning musical The Drowsy Chaperone, written with songwriting partner, Lisa Lambert. The Drowsy Chaperone was their first collaboration. In 1999 Lambert asked Morrison to work on a musical to perform at the wedding stag party of their friends, Bob Martin and Janet Van De Graaff. Also a part of this original writing team was filmmaker, Don McKellar. That was the first incarnation of The Drowsy Chaperone. This was followed by an expanded production of the show at the Toronto Fringe festival, where Martin joined as a co-writer and performer.
