Information about old shows

I was doing some research on shows that have played at Broadway theaters, especially at The Minskoff. I was wondering if anyone knew about any websites that would offer me information about the actress/actors that were in the shows and what they are doing now? I was also wondering if anyone knew where to get the songs from these shows. I know it will be hard to find anything as The Minskoff has a history of bad shows, but I was curious if anyone knew anything...

If you search the word "Minskoff" the theatre will come up as one result.

Click that link and you'll get a list of every production that has played at the Minksoff. Then click any of the show links and you'll get details about that production, including songs for some of the shows.
