Jane Krakowski A Chorus Line (AllyMcBeal)

Help me out - did Jane Krakowski sing "Dance Ten, Looks Three" in Ally McBeal? I think I remember her singing it in the show, but I may be thinking of some totally different appearance elsewhere. If so, does anybody know what episode/season? I can't find it on YouTube.

Her "The Music and the Mirror" is there, though, and of course worth a watch.

Thank you!

It's coming back to me now...it makes sense the A Chorus Line songs were in the same episode...the show was so music-heavy, I couldn't recall, and was starting to think I had imagined it. I'm way overdue a re-watch of this series.
