There is no better reason for the invention of the Internet than the Website Blue Gobo. I don't know of a better resource for video clips of classic scenes from Broadway theater. For a theater lover, it is like finding gold.
These clips are taken from talk shows, awards shows, the Macy Thanksgiving Day Parade, and where ever else Broadway performers promoted their shows, and often this is all that is left of the original production. Why Congress has not passed a law requiring all Broadway shows to be immortalized on video is beyond me.
Suffice to say, I love this site and find a new treasure on every visit. Clips are searchable by decade and title, and the home page features highlights of recent clips. Take some time and explore.
For instance, click here to view a clip from the 1991 production of The Secret Garden and see if you recognize a very young John Cameron Mitchell, who would later go on to become Hedwig and the Angry Inch.
