Callahan's cover of Cohen's "So Long, Marianne" is the second Cohen cover to be shared over the past 24 hours, after Haim's take on "If It Be Your Will".
The Cohen cover is the B-side to his version of Lee Clayton's "If You Could Touch Her At All".
Back in August, the Shepherd In A Sheepskin Vest singer/songwriter also covered Silver Jews' "I Remember Me" as a tribute for the late David Berman.
