Thomas continued to record and toured internationally, billing himself as "The World's Oldest Teenager" and describing himself as "the funkiest man alive". He "drew upon his vaudeville background to put [his songs] over on stage with fancy footwork that displayed remarkable agility for a man well into his fifties", and usually performed "while clothed in a wardrobe of hot pants, boots and capes, all in wild colors."  He continued as a DJ at WDIA until 1974, and worked for a period at WLOK before returning to WDIA in the mid 1980s to co-host a blues show. He appeared regularly on television and recorded albums for various labels. Thomas performed regularly at the Porretta Soul Festival in Italy; the outdoor amphitheater in which he performed was later renamed Rufus Thomas Park.  He played an important part in the Stax reunion of 1988, and appeared in Jim Jarmusch's 1989 film Mystery Train, Robert Altman's 1999 film Cookie's Fortune, and D. A. Pennebaker's documentary Only the Strong Survive. Thomas released an album of straight-ahead blues, That Woman is Poison!, with Alligator Records in 1990, featuring saxophonist Noble "Thin Man" Watts. In 1996, he and William Bell headlined at the Olympics in Atlanta, Georgia. In 1997, he released an album, Rufus Live!, on Ecko Records. In 1998, he hosted two New Year's Eve shows on Beale Street.  In 1997, to commemorate his 80th birthday, the City of Memphis renamed a road off Beale Street, close to the old Palace Theater, as Rufus Thomas Boulevard. He received a Pioneer Award from the Rhythm and Blues Foundation in 1992, and a lifetime achievement award from ASCAP in 1997. He was inducted into the Blues Hall of Fame in 2001.
