The 1968 rock musical "Hair" gets a 2010 update during "Twitter Night," a one-night departure from Manoa Valley Theatre's ban on electronic devices.

"Hair" tells the story of young Americans' quest for love and peace during the Vietnam era, with a score that includes "Aquarius," "Let the Sun Shine In," "Be-In (Hare Krishna)," "Good Morning Starshine" and "Hair."
