In 1996, MacIsaac toured the United States as an opening act for The Chieftains. On a 1997 Late Night with Conan O’Brien appearance, his leg kick lifted his kilt high enough that his genitals were visible to the studio audience, although they were blurred out in post-production before the actual broadcast.
