Treasure trove

Applause, applause to Jeremy Aufderheide, the Web master behind BlueGobo.com, an extraordinary Web site featuring an enormous collection of Broadway-musical video clips stretching back to the 1950s.Clips come primarily from variety show performances, Tony Awards telecasts and promotional spots, and the site is a good way to lose a few hours of your life.As we head into Tony Awards week, spend a little time with some musicals of the past.To get you started, here's a crusty old favorite of mine: Steve Lawrence and Eydie Gorme sining the title song from their one and only Broadway show, Golden Rainbow. They make it seem so effortless.
