Singer Mark Lanegan of Screaming Trees contributed vocals and additional lyrics to "Long Gone Day".

Barbara Davies of Rolling Stone called it a "lustrous duet in which Staley trades verses with Screaming Trees vocalist Mark Lanegan, whose honeyed growl is in its element among the cool percussion, sensitive sax and pliant bass."

She added, "That Mad Season are capable of tremendous power and also succeed with such a subtle song proves that the band is – at times – more than the mere sum of its parts.

"[1] "Long Gone Day" was first performed live at the band's April 22, 1995 concert in Seattle, Washington at the Crocodile Cafe.

[2] A performance of "Long Gone Day" can be found on the Live at the Moore home video release.
