Example Input: Question: What was the most famous song by the person who also had covered Dixon's song? Passage:A mixture of songs that inspired his own musical development, together with some of his own compositions, allied to a backing band and orchestra (The Caledonia Soul Orchestra) and several performances (as noted in the album's liner notes) that were recorded in concerts at The Troubadour in Los Angeles, California (2427 May 1973), the Santa Monica Civic Auditorium (29 June 1973) and The Rainbow (2324 July 1973) in London. These performance result in what Myles Palmer of the Times reviewed as demolishing "all barriers between the soul, blues, jazz and rock genres". The songs chosen went back to his days with Them with versions of "Gloria" and "Here Comes the Night". His first solo hit "Brown Eyed Girl" was performed but not included on the album until the reissue in 2008. M. Mark called the album "an intelligent selection of songs that draws on six of Morrison's records and five of the musicians he learned from." These musicians were Bobby Bland ("Ain't Nothing You Can Do"), Ray Charles ("I Believe to My Soul"), Sam Cooke ("Bring It On Home to Me"), two songs by Sonny Boy Williamson II ("Help Me" and "Take Your Hands Out of My Pocket") and a cover of a Willie Dixon song, "I Just Want to Make Love to You", which was popularized by Muddy Waters.

Example Input: Question: How many years after the Clairvaux was found, was the Margam Abbey founded? Passage:The abbey was founded in 1147 as a daughter house of Clairvaux by Robert, Earl of Gloucester, and was dedicated to the Blessed Virgin Mary. Early Christian crosses found in the close vicinity and conserved in the nearby Margam Stones Museum suggest the existence of an earlier Celtic monastic community. The founding abbot was William of Clairvaux. The third abbot, Conan, enjoyed the praise of Giraldus Cambrensis, whom he appears to have entertained prior to his official visit with Baldwin of Forde, Archbishop of Canterbury, to preach the Crusade in 1188. Conan (or Cunan) contributed to Patristic literature, as he is credited with the capitula or chapter-headings prefixing each section of St. Bernard's Sermons on the Song of Songs, one of the works for which that author was titled a Doctor of the Church.
