Emmy Award winner and Tony nominee Burnett plays the mother of Sue Sylvester (Jane Lynch) and gets to duet with her on the satirical Leonard Bernstein-Betty Comden-Adolph Green ballad "Ohio" from Broadway's Wonderful Town, with some special lyrical changes referring to mother Doris' Nazi-hunting past.
Other tracks feature Matthew Morrison on "Sway," Lea Michele and Cory Monteith on "Marry You" and Monteith on "Just the Way You Are."
