The 9:30 PM concert includes Lindsay's husband, Kevin Massey (Memphis); Ashley Spencer (Rock of Ages); Kirsten Scott (Big Fish); Santino Fontana (Cinderella) and his girlfriend, Jessica Hershberg (Cinderella); Drew Gehling (On a Clear Day…) and his wife, Sara Jean Ford (The Phantom of the Opera); Patrick Cummings (Happiness) and his girlfriend, Alessa Neeck (Cinderella); Thea Brooks (Dirty Dancing); Aaron Albano (Newsies); Antwayn Hopper (Hair); Joseph Anthony Byrd (The Lion King); Devin Ilaw (Les Misérables); Stephen Joshua Thompson; and musical director Benjamin Rauhala.

A Very Broadway Valentine's Day, which celebrates Broadway romance — both on and off stage — also features the bluegrass trio Shubert Alley, composed of Massey (Memphis) and his brother, Patrick Massey, as well as Jamison Scott (Spider-Man Turn Off the Dark).

Performers are accompanied by Rauhala on the keys and Charlie Rosen (One Man, Two Guvnors), who alternates on bass, acoustic guitar and drums.

Proceeds from the evening will be donated to Hope4Gavin to support two-year-old Gavin Strand in his battle with cancer. Strand is the son of musical director Rauhala's cousins, Katie and Dan Strand, and was diagnosed with Acute Lymphoblastic Leukemia the day after his first birthday. He is in remission, but continues to receive chemotherapy and takes over 100 oral medications a month. He will finish treatment in July.
