Example Input: Question: What year did Cash record "Big Iron"? Passage:Robbins has been honored by many bands, including the Grateful Dead who covered "El Paso" and Bob Weir & Kingfish who covered "Big Iron". The Who's 2006 album Endless Wire includes the song "God Speaks of Marty Robbins". The song's composer, Pete Townshend, explained that the song is about God deciding to create the universe just so he can hear some music, "and most of all, one of his best creations, Marty Robbins." The Beasts of Bourbon released a song called "The Day Marty Robbins Died" on their 1984 debut album The Axeman's Jazz. Both Frankie Laine and Elvis Presley, among others, recorded versions of Robbins' song "You Gave Me a Mountain", with Laine's recording reaching the pop and adult contemporary charts in 1969. Though Elvis never recorded any of Robbins' songs in the studio, he was a big fan and recorded "You Gave Me a Mountain" live in concert several times; it appeared on 15 Presley albums. Johnny Cash recorded a version of "Big Iron" as part of his American Recordings series, which is included in the Cash Unearthed box set. Cash also recorded other songs by Robbins, including "I Couldn't Keep From Crying", "Kate" and "Song Of The Patriot".

The song, originally released on Robbins' 1959 album Gunfighter Ballads and Trail Songs, gained renewed popularity following its use in the video game .
