Megan Mullally was in another Broadway play in 1995. It was called 'How To Succeed In Business Without Really Trying' or 'H2$' for short. It starred Matthew Broderick (from Ferris Bueller's Day Off and Inspector Gadget) as a window washer who uses a guidebook to succeed in business without really trying. Megan played Rosemary, a secretary who developes a crush on Matthew's character, J. Pierrepont Finch. She sings in 7 songs. I have placed WAVS of these below. The pictures are from the CD booklet. Also, on an interesting note, one of the men who plays a writer is called Jack Hayes. Coincidence? Well, yes, but it's interesting none the less.
