Millie Kirkham -- a backup singer for Elvis Presley who featured on numerous vintage rock and country songs from the '50s to the '80s -- has passed away at age 91. Kirkham died on Sunday in Nashville after complications from a stroke she suffered last week.

Kirkham lent her high voice to recordings from Roy Orbison, George Jones, Bob Dylan, Johnny Cash and Patsy Cline, but her most recognizable contribution might be her backup vocals on one of Elvis' Christmas classics. Her voice provides the "woo-we-woo" sound on Presley's "Blue Christmas" from 1957. She also sang on his hits "Don't" and "(You're the) Devil in Disguise."
