Question:

Jeckyll and hyde fans!!??

why does that lady sing "no one knows who I am?"

Best Answer - Chosen by Asker: My personal opinion is that the song iis included to carry out the overall themes of the libretto; Isolation, Deception,Hypocrisy, etc.
In addition to informing the audience regarding the specific character, the song also serves to give insights into the world of J/H.
On another note, my favorite is "This is the Moment" :-)
