On XM 28 (On Broadway) and XM 200 (XM Live) from 11AM to 11PM EST on Saturday March 19, they are presenting a live broadcast of the "Symphony Stage" Tribute to Stephen Sondheim from New York. I've been listening for the last 2 hours plus, and so far it's been quite enjoyable. It's primarily music, but also some interview segments, with the complete 12-hour tribute being broadcast live. I find some of Stephen Sondheim's music to be rather strange, but somehow it all seems less strange in a show such as this one. This is what radio should be, and this is what XM is all about. It's scheduled to last 12 hours, but obviously could be slightly shorter or longer, but it should run until approximately 11PM EST tonight. All you Stephen Sondheim fans out there should try to check this broadcast out. Enjoy! Steve K.
