Listen as the young folk singer unwinds and plays a song for you. Most of the 50 tracks in this compilation were recorded for the M. Witmark & Sons publishing company.

Nathan Lane hosts the PBS special that has Tony Award nominees and winners performing tunes from Broadway’s beloved musicals for President Obama and his wife. Performers include Elaine Stritch (“A Little Night Music”), Marvin Hamlisch (“A Chorus Line”), Idina Menzel (“Wicked”), Brian d’Arcy James (“Next to Normal”), Chad Kimball (“Memphis”) and Karen Olivo (“West Side Story”). Absent from the lineup: McKinley High’s music director Will Schuester (Broadway performer Matthew Morrison), which means it will be a telecast devoid of his bad rapping skills.  (Tina Fineberg / Associated Press)
