input: At age 49 in the 1989 Masters, Trevino shot an opening round five-under-par 67 to become the oldest man ever to lead the field after a round in the tournament. It came despite Trevino's words 20 years earlier, when he said after the 1969 Masters: "Don't talk to me about the Masters. I'm never going to play there again. They can invite me all they want, but I'm not going back. It's just not my type of course." Trevino said that he felt uncomfortable with the atmosphere at the Augusta National club and that he disliked the course because his style of play, where he liked to fade shots left to right, was not suited to the course. Trevino did not accept invitations to the Masters in 1970, 1971 and again in 1974. In 1972, after forgoing the previous two Masters tournaments, he stored his shoes and other items in the trunk of his car, rather than use the locker room facilities in the clubhouse. Trevino complained that had he not qualified as a player, the club would not have let him onto the grounds except through the kitchen. But he later described his boycott of the Masters as "the greatest mistake I've made in my career" and called Augusta National "the eighth wonder of the world." After his opening round of 67 in the 1989 Masters, Trevino finished the tournament tied for 18th place. His best finish at the Masters was a tie for 10th place twice: in 1975 and in 1985.

input: Two records were released that were neither cover versions of nor answers to Thornton's release, yet used a similar melody without any attribution to Leiber and Stoller. The first was Smiley Lewis's "Play Girl", credited to D. Bartholomew and released by the Imperial Records label (Imperial 45-5234) by the end of March 1953. Described as a "stomping uptempo boogie rocker", it began: "You ain't nothin' but a Play Girl / Staying out all night long". In April 1955, female impersonator Jesse "Big 'Tiny'" Kennedy recorded "Country Boy" accompanied by His Orchestra that was released by RCA's Groove Records (Groove 4G-0106) by May 21. While credited solely to Kennedy, this song has a similar melody to "Hound Dog": "'Country Boy' has a deceptively slouching flip on the 'Hound Dog' motif - this time with Tiny proclaiming proudly that he 'ain't nothing but a country boy'". In the early 1970s Robert Loers, owner of Dutch label Redita Records, found a song with the same melody as "Hound Dog" called "(You Ain't Nuttin' But a) Juicehead" on an anonymous acetate at Select-o-Hits, the Memphis distributorship owned by Sam Phillips' brother, Tom, where Sun artifacts were stored. When Juice Head first appeared on a Redita Records LP [in 1974], it was credited to Rosco Gordon. But it's not Rosco. It simply is not him. Really. Even Rosco confirmed that. It might not even be a Memphis Recording Service demo. Just substitute the words "Hound Dog" for "Juice Head" and what have you got? Of course the inspiration for this song came from Big Mama Thornton's "Hound Dog" or perhaps even from Rufus Thomas' "Bear Cat". But the song's other parent is Eddie Vinson's slowed down "Juicehead Blues" which harks to the previous decade...If indeed this originated from Sam Phillips' studio, it was nothing that Phillips needed to touch because it was another lawsuit waiting to happen." Philip H. Ennis sees "Two Hound Dogs", which was recorded on May 10, 1955, by Bill Haley & His Comets (Decca 29552), as a response to Thornton's recording. While not an answer record in the traditional sense, the lyric characterized "Rhythm" and "Blues" as the titular "Two Hound Dogs," an apparent testament to the stature of "Hound Dog."

Elena Temnikova (Russian: Elena Temnikova, born 18 April 1985 in Kurgan, Russia) came to media prominence as a contestant on the Channel One talent show Star Factory in 2003. She was spotted by Maxim Fadeev, the main producer of Star Factory, and signed to his recording company Monolit Records. Although Temnikova released two disco singles, "Begi" and "Taina", she did not continue her solo career and joined Serebro instead.
