On 8 April 2017, Deysel made his debut for Munster when he started against Scottish side Glasgow Warriors in a 2016–17 Pro12 fixture. Munster won 10–7, with Deysel being replaced by Peter O'Mahony in the 42nd minute.

Example Input: Question: Did "Don't Let Me Down" win any awards? Passage:Hardesty's solo recordings began in 1957; the first two, organized by the guitarist Mickey Baker, were never released are not known to exist. Twelve songs were recorded on January 15, 1958, at Cosimo Matassa's studio in New Orleans for Wing Records, a subsidiary of Mercury Records, but were never released until the 2012 CD The Domino Effect was issued worldwide by Ace Records (United Kingdom). The first time that Hardesty's name appeared on a single was with the Canadian vocal quartet the Diamonds, "Don't Let Me Down" (also known as "Chick-Lets"), which was recorded on March 4, 1958, and released the following month as Mercury 71291. In 1959, Hardesty recorded four tracks in New York City with Hank Jones. Two were released as a single on Paoli, the only release from this label; they were also released shortly after by Mutual, both labels having connections to Philadelphia. The Mutual release was listed on Philadelphia radio station WIBG's Future Forty chart for November 2, 1959, but did not chart elsewhere. The four tracks were purchased by King Records in 1961 and were re-released as two 45s by Federal Records in April and June 1961. Hardesty recorded four more songs in October 1961, which were released in 1962 by Federal; two are not instrumentals and had vocals by the New Orleans guitarist Walter "Papoose" Nelson. Hardesty co-wrote the title track of Fats Domino's 1964 album, Fats on Fire.

Example Input: Question: Did the song that Homer sings place in the top 10 of the US charts? Passage:Additionally, Homer sings Billy Joel's 1983 song "Uptown Girl". After drinking the tainted juice, Grampa and Jasper sit on a bench, laughing like the title characters from the series Beavis and Butt-head, while Flanders hallucinates skeletons and dancing bears (images associated with the Grateful Dead), marching hammers (from Pink Floyd's 1982 film Pink Floyd—The Wall) and The Rolling Stones' lips and tongue logo. Mr. Burns' film is credited as "An Alan Smithee Film", a reference to the Alan Smithee pseudonym credit used by directors who wanted to be disassociated from a film on which they had lost creative control, to the detriment of the final product. When Barney drinks alcohol to prevent the bad effects from the tainted juice, a pink elephant comes to his rescue, referencing the scene in Dumbo where Dumbo and Timothy drink alcohol and see pink elephants. Seth and Munchie's dog is named Ginsberg, thought to be a reference to beat poet Allen Ginsberg. Homer putting the flowers in the policemen's rifles is a reference to the iconic October 22, 1967 Life magazine picture, "Flower Power" by Bernie Boston.
