When you stay at Brook Farm Inn, Lenox Massachusetts this weekend, you can enjoy  “The Piano Men,” a musical journey through the ’70’s featuring music of Billy Joel and Elton John.  It’s at the Colonial Theatre in Pittsfield on Satuday evening. This is a multimedia tour through the 70’s featuring not only the music, but tidbits and trivia on the screen, like popular cars and toys of the era. Sounds like a great evening of nostalgia.
