Love and marriage go together sweetly in Tom Jones and Harvey Schmidts much adored I Do! I Do! The story covers 50 years of marriage between Agnes and Michael Snow, through the yummy years of young love, the hair-pulling and hand-wringing of parenthood, and, of course, the wildness of an affair. Later comes the lonely empty nest and, finally, the loving tenderness of old age. This Tony Award-nominated homage to marriage is told by two actors through charming, touching songs. 7:30 p.m. Thursdays, 8 p.m. Fridays and Saturdays, 3 p.m. Sundays. Through April 10. Texas Repertory Theatre, 14243 Stuebner Airline. For information, call 281-583-7573 or visit www.texreptheatre.org. $35 to $45.
