This was the group's first major hit, and like their next one, "Dust In The Wind
," it was a last minute addition to the album. Kerry Livgren wrote the song just two days before they started recording Leftoverture
. At that point, the band was polishing the songs they had, not bringing in new ones. "I've got one more song that you might want to hear," he told the band, and when he played "Carry On," they knew it was a hit and made it the lead track on the album.
