W.A.S.P. frontman Blackie Lawless has explained why he chose to perform "Mr. Cool", a song written when he was 18 and never previously played live, during the band's current "1984 To Headless" tour. The track originated as a demo from his pre-W.A.S.P. band SISTER and later evolved into "Cries In The Night" on 1985's "The Last Command" album. Speaking at a VIP Q&A before the band's 12 September show in Riverside, California, Lawless said the song carries painful personal history, as a former bandmate sold the demo for $5,000 without his knowledge and later sued him for copyright infringement.

Lawless said he is performing the song purely "for me", noting most fans will be unfamiliar with this original version unless they have sought it out on YouTube. The "1984 To Headless" US and Canada tour, supported by KK's Priest, opened on 10 September in El Cajon, California, with a 17-song setlist drawn largely from W.A.S.P.'s first four albums (1984–1989) and featuring elaborate stage visuals inspired by the album artwork. The tour, first announced in February 2026, again offers VIP packages including meet-and-greets with Lawless.
