Question:
Stephen Ray Vaughan (October 3, 1954 - August 27, 1990) was an American musician, singer, songwriter, and record producer. In spite of a short-lived mainstream career spanning seven years, he was one of the most influential guitarists in the revival of blues in the 1980s. AllMusic describes him as "a rocking powerhouse of a guitarist who gave blues a burst of momentum in the '80s, with influence still felt long after his tragic death." Born and raised in Dallas, Texas, Vaughan began playing guitar at the age of seven, inspired by his older brother Jimmie.
In September 1970, Vaughan made his first studio recordings with the band Cast of Thousands, which included future actor Stephen Tobolowsky. They recorded two songs, "Red, White and Blue" and "I Heard a Voice Last Night", for a compilation album, A New Hi, that featured various teenage bands from Dallas. In late January 1971, feeling confined by playing pop hits with Liberation, Vaughan formed his own band, Blackbird. After growing tired of the Dallas music scene, he dropped out of school and moved with the band to Austin, Texas, which had more liberal and tolerant audiences. There, Vaughan initially took residence at the Rolling Hills Country Club, a venue that would later become the Soap Creek Saloon. Blackbird played at several clubs in Austin and opened shows for bands such as Sugarloaf, Wishbone Ash, and Zephyr, but could not maintain a consistent lineup. In early December 1972, Vaughan left Blackbird and joined a rock band named Krackerjack; he performed with them for less than three months. In March 1973, Vaughan joined Marc Benno's band, the Nightcrawlers, after meeting Benno at a jam session years before. The band featured vocalist Doyle Bramhall, who met Vaughan when he was twelve years old. The next month, the Nightcrawlers recorded an album at Sunset Sound Recorders in Hollywood for A&M Records. While the album was rejected by A&M, it included Vaughan's first songwriting efforts, "Dirty Pool" and "Crawlin'". Soon afterward, he and the Nightcrawlers traveled back to Austin without Benno. In mid-1973, they signed a contract with Bill Ham, manager for ZZ Top, and played various gigs across the South, though many of them were disastrous. Ham left the band stranded in Mississippi without any way to make it back home and demanded reimbursement from Vaughan for equipment expenses; Ham was never reimbursed. In 1975, Vaughan joined a six-piece band called Paul Ray and the Cobras that included guitarist Denny Freeman and saxophonist Joe Sublett. For the next two-and-a-half years, he earned a living performing weekly at a popular venue in town, the Soap Creek Saloon, and ultimately the newly opened Antone's, widely known as Austin's "home of the blues". In late 1976, Vaughan recorded a single with them, "Other Days" as the A-side and "Texas Clover" as the B-side. Playing guitar on both tracks, the single was released on February 7, 1977. In March, readers of the Austin Sun voted them as Band of the Year. In addition to playing with the Cobras, Vaughan jammed with many of his influences at Antone's, including Buddy Guy, Hubert Sumlin, Jimmy Rogers, Lightnin' Hopkins, and Albert King. Vaughan toured with the Cobras during much of 1977, but near the end of September, after they decided to strive for a mainstream musical direction, he left the band and formed Triple Threat Revue, which included singer Lou Ann Barton, bassist W. C. Clark, and drummer Fredde Pharaoh. In January 1978, they recorded four songs in Austin, including Vaughan's composition "I'm Cryin'". The thirty-minute audio recording marks the only known studio recording of the band.

Answer the question at the end by quoting:

Joseph Guilherme Raposo, OIH (February 8, 1937 - February 5, 1989) was a Portuguese-American composer, songwriter, pianist, television writer and lyricist, best known for his work on the children's television series Sesame Street, for which he wrote the theme song, as well as classic songs such as "Bein' Green" and "C Is For Cookie". He also wrote music for television shows such as The Electric Company, Shining Time Station and the sitcoms Three's Company and The Ropers, including their theme songs. In addition to these works, Raposo also composed extensively for the DePatie-Freleng Enterprises such as Halloween Is Grinch Night, Pontoffel Pock, Where Are You? and The Grinch Grinches the Cat in the Hat.
Raposo is best known for the songs he wrote for Sesame Street from its beginning in 1969 through the mid-1970s, and also for a time in the 1980s. He wrote the "Sesame Street Theme" - various versions of which have opened every episode - as well as many of its most popular songs, such as "Bein' Green", "C is for Cookie", "Sing" and "ABC-DEF-GHI". A version of "Sing" recorded by The Carpenters in 1973 reached #3 on the Billboard top singles chart. For many years, most of the music used in Sesame Street's film segments was also written -- and often sung -- by Raposo. Aside from his musical contributions, Raposo performed several uncredited stock characters on Sesame Street during the early 1970s. According to his son Nicholas in a 2002 telephone conversation, Joe Raposo usually chose to portray anonymous, silly characters in these segments, which were nearly always produced on 16 mm film. He also did voice-overs for a few animated segments. The Sesame Street character Don Music maintained a framed and autographed glamour photograph of Raposo on the wall of his Muppet atelier. Raposo was very fond of sweets according to many who knew him. One favorite food of his was cookies. It has been rumored the Wheel-Eating Monster created for commercial advertisers in the 1960s by Jim Henson may have been altered by Henson specifically into a "cookie" monster after Henson observed Raposo's unusual propensity for cookies; this has never been substantiated. Raposo was actually the first puppeteer to operate Cookie Monster on television for Sesame Street. His widow Pat Collins-Sarnoff celebrated his life with a milk and cookies reception. One of Raposo's Sesame Street compositions, "The Square Song", was used in the film Close Encounters of the Third Kind.

how many time did he appear?
16 mm film.
