“Bruce Warren provides the evening’s best performances as Gus the theatre cat, the operatic GrowlTiger, and Bustopher Jones. Warren cannot be over praised for his tone, clarity, phrasing and interpretation of Gus’ solo, which is, at least in his hands, the wittiest and most human lyric in the show. His Italian aria-like GrowlTiger number is beautifully sung.”
-Bob Rendell, TalkinBroadway.com
“Act I highlights include Bustopher Jones (delightfully portrayed with pompous aplomb by the versatile Bruce Warren, who later also shines as Asparagus, the Theatre Cat, and GrowlTiger).”
-John Busbee, Art Scene Iowa
“Vocal master Bruce Warren morphs beautifully from the fragile and tattered older Gus to robust, operatic sensation GrowlTiger.”
-Janet French, The Star Phoenix
“As Gus/Growltiger, Bruce Warren's baritone voice soars in ‘Gus: The Theatre Cat’ and ‘GrowlTiger's Last Stand’."
-Misha Davenport, Chicago Sun Times
“Bruce Warren delivers a stunningly sweet portrayal of Asparagus, the Theatre Cat. Warren takes Gus from meek and feeble to bold and brash within two songs.”
-Erica Kritt, The Baltimore Towerlight
“There is unexpected pathos particularly from Bruce Warren's touching portrayal of Gus the Theatre Cat.”
-Marc Acito, The Portland Oregonian
