Ian MacKaye is also the best friend of Henry Rollins. In Rollins' autobiography "Get in the Van" he credits Ian with being the inspiration for Rollins joining Black Flag. Evidently Ian gave him a pep talk and told him to take this opportunity (to tour with the band) despite all of his worries about making the bills with his then crap ass job. Thus Ian is not only a respected punk deity in his own right he also is directly responsible for the man with the neck.
