Input: Consider Input: Question: How many seasons did the television show that Earl Gaines appeared on air? Passage:Breaking away from the confines of the group, Gaines became part of the 1955 R&B Caravan of Stars, with Bo Diddley, Big Joe Turner, and Etta James. Their tour culminated with an appearance at New York's Carnegie Hall. Without any tangible success, Gaines recorded for the Champion and Poncello labels for another few years, as well as joining Bill Doggett's band as lead vocalist. In 1963, he joined Bill "Hoss" Allen's repertoire of artists, and by 1966 had issued the album The Best of Luck to You, seeing the title track reach the Top 40 in the US R&B chart. He appeared on the television program The !!!! Beat, and later released material for King and Sound Stage 7, including his cover version of "Hymn Number 5". Recordings made between 1967 and 1973 for De Luxe were reissued in 1998. On many of his De Luxe recordings in the late 1960s and early 1970s, Gaines was backed by Freddy Robinson's orchestra.

Input: Consider Input: Question: In what years did the Calgary Dinos win the Vanier Cup? Passage:During the following off-season in 2015, UBC Athletics would draw the Dinos head coach, Blake Nill away from the Calgary Dinos in what was the most high profile coaching change that year. Nill's impact was immediate as he was able to recruit quarterback Michael O'Connor, who was the ranked the sixth best quarterback by ESPN among the 2014 recruiting class. The Thunderbirds achieved a turnaround in Nill's debut season at the UBC helm to finish the 2015 regular season with a 62 record, placing second in the CWUAA standings. During the ensuing post-season drive of three straight single-elimination playoff games on the road, UBC upset the heavily favoured Calgary Dinos in the Hardy Cup game at Calgary; then defeated the St. Francis Xavier X-Men to earn its historical first Uteck Bowl victory at Antigonish, to advance to the national title game. In the 51st Vanier Cup championship, the Thunderbirds narrowly defeated the defending CIS champion Montreal Carabins, by scoring the game's last possession field goal to end the fourth quarter. The victory was UBC's fourth Vanier Cup overall, tying the Calgary Dinos for the all-time record among CWUAA member universities.
