It's funny: the roles seem to choose me more often than I them. Neither of my recent auditions got me a callback, but Fort Bend Theatre called me to invite me to step into the role of Mr. Wilson in Annie Get Your Gun. This is how I wound up as Freddy in My Fair Lady. Most of my other roles have resulted from being invited by someone involved with the show, rather than my finding out about it and going.
Still, my favorite role so far was one I chose to go after: Lumiere. I hope there will be another, one of these days.
The show is March 6, 7, and 8 at the Stafford Centre. Information at the link.
