PHOTO FLASH: FROZEN's Robert Lopez Plays 'Let It Go' As Marie's Crisis Crowd Sings Along

As New York's only piano bar that exclusively caters to the showtune-loving crowd, it's not unusual to see Tony-winners taking in an evening belting out numbers with the gang at Marie's Crisis.

Oscar-winners are a bit of a rarer sight, but last night a pair of them excited the crowd as the wedded songwriting team of Robert Lopez and Kristen Anderson-Lopez joined the fun. Married since 2003, the couple nabbed the 2014 Best Song Oscar for "Let It Go," from their score for the smash movie musical FROZEN. The stage version of FROZEN is schedule for Broadway during the spring of 2018 after a premiere engagement at the Denver Center for the Performing Arts during the summer of 2017.

A Marie's Crisis favorite, actor/singer Franca Vercelloni, was the pianist working the evening shift, but she was happy to bend the rule about customers not being allowed at the keyboard so that Robert Lopez could play their Oscar-winning hit. He encored with "There's a Fine, Fine Line," from the Tony-winning score of AVENUE Q, which he penned with Jeff Marx.

Pictured below are Kristen Anderson-Lopez, Robert Lopez and Franca Vercelloni.

Robert Lopez did leave a clue to his whereabouts to his Twitter followers with this pic of the rarely-used Marie's Crisis television.
