Actress and singer Barbra Streisand appeared on The Tonight Show Monday for the first time since 1963, and sang a duet with host Jimmy Fallon. The pair sang Elvis Presley’s hit song “Love Me Tender,” with Fallon standing in for “the king” complete with the appropriate hair-do and sunglasses. Streisand’s appearance on The Tonight Show was to promote her new duets album, “Partners,” which has tracks that sample Elvis recordings.
