Religion still held a strong place in Dylan's work, but as 1981 came to a close, his religious songs gave way to more secular material. During concerts in the summer of 1981, he covered Dave Mason's "We Just Disagree" and Dion's "Abraham, Martin & John". Some fans took the latter as a veiled ode to John Lennon, who was shot and killed the preceding winter, but in fact most of Dylan's performances of this song had been in the month immediately preceding Lennon's death, as a staple in the November–December 1980 US tour. Clinton Heylin notes, "Dylan was audibly coming to the end of this particular road."
