A teenage Elvis impersonator from Quebec performed during a celebration for the late icon's 79th birthday at Graceland today.

David Thibault, 16, sang Happy Birthday and participated in the cake-cutting at the event at Elvis Presley's longtime Memphis home. He also taped a segment with Jenna Bush Hager, daughter of former U.S. president George W. Bush and a correspondent for the Today show.

Thibault gained fame after his singing of Blue Christmas garnered millions of views on YouTube.

Remembering The King

Other guests at the Graceland party included television and radio personality Wink Martindale. He recalled the day nearly 60 years ago when Presley's first single, That's All Right, played for the first time on the radio.

It was July 8, 1954, and a fresh-faced Martindale was working as a disc jockey at WHBQ in Memphis. He was at the studio when legendary producer Sam Phillips brought by an acetate copy of the song Presley cut at Phillips' Sun Records.

'[Hearing That's All Right for the first time] was almost like an out-of-body experience' - Wink Martindale

DJ Dewey Phillips — no relation to Sam — played the song on his influential Red, Hot and Blue radio show, and rock 'n' roll history was made.

"It was almost like an out-of-body experience," Martindale told Presley fans at Wednesday's gathering.

"That was the beginning of Presley-mania."

Bush Hager, Thibault and Martindale participated in the cake-cutting along with producer Knox Phillips, who is Sam Phillips' son and a member of the Memphis Music Hall of Fame.

Martindale was a longtime friend of Presley, who dated Martindale's wife Sandy before they married. After his days in Memphis, Martindale went on to TV fame as host of Teenage Dance Party and the game shows Gambit and Tic Tac Dough.

Presley was born in Tupelo, Miss., on Jan. 8, 1935, and moved to Memphis with his parents at age 13. He was 42 when he died Aug. 16, 1977.
