Signature Theatre long has been known for staging Broadway-caliber works by that genius, Stephen Sondheim.
Unfortunately, in the current production of Merrily We Roll Along, Signature's "signature" gets blurred.
If You Go Merrily We Roll Along runs through Oct. 14 at Signature Theatre, 4200 Campbell Ave., Arlington, Va. Showtimes are 7:30 p.m. Tuesdays-Wednesdays; 8 p.m. Thursdays-Fridays; 2 p.m., 8 p.m. Saturdays; 2 p.m., 7 p.m. Sundays. $40-$69. Call 703-820-9771 or go to signature-theatre.org.
