NBC’s upcoming James Burrows special, which basically was announced as an incomplete Friends reunion last week, now has a much more robust lineup, with several TV comedy teams reuniting for the salute.

Must See TV: A Tribute to James Burrows will include five Friends stars coming together, as well as reunions from Cheers, Will & Grace, Frasier and Taxi, among others. Also of note: Charlie Sheen is involved, along with his former Two and a Half Men co-star Jon Cryer.
