Michelle Obama enters Memphis at Broadway's Shubert Theater, March 21, 2010

*While her husband was at the White House becoming the first president in US history to get a health care passed in Congress, the First Lady and First Daughters were in New York taking in a Broadway play.

Michelle Obama – with Sasha, 8, and Malia, 11, and about a dozen other people in tow – went to a Sunday matinee of the musical “Memphis,” according to the New York Daily News.

Security blocked off 44th Street outside the Shubert Theatre when their motorcade arrived. Obama, the girls and their friends were ushered in through a side door to seats reserved in the first four rows of the theater.

“They didn’t make an announcement but when they came in, everybody noticed and started taking pictures. Then people started clapping too and there was a standing ovation for them,” according to audience member Terri Mertz.

“I knew she was tall but I didn’t realize she was that tall!,” said Mertz, referring to the First Lady, who was wearing a black dress.

Secret Service members, triggered by the rash of audience members who reached for cellphones and digital cameras to photograph Sasha and Malia, warned at intermission that they would confiscate anyone who tried to take any more pictures.

Shortly before intermission, the Obamas and their entourage were escorted out and returned after the other audience members were seated. After the show, the audience remained seated as they again walked up the aisle and the girls smiled and waved to their fellow theater-goers.

“Memphis” tells the story of a white DJ, Huey Calhoun, in 1950s segregated Tennessee; his love for a black singer, Felicia Powell, and the then underground sound that gave birth to rock and roll. Watch a clips below.
