Must say, I thought the same thing. Just awful - in a show with otherwise good casting - yep "What were they thinking?"
Also, I just watched the videos of Bebe Neuwirth and of Liza/Goldie. Wow - that Bebe was slinky and almost - dare I say it? - Dirty (in a good way!). As lousy as the video quality was, it just about melted my computer screen! I'm mainly familiar with her from Madam Secretary, and I knew she was a Broadway star, but yowza!
On the other hand, the Liza/Goldie version didn't do it for me. Yeah, Liza is a great singer and both women could move but it was almost too chipper and cheerful, and despite their cool outfits, not sexy to me in the least bit.
