HBO's name stands for Home Box Office, and in the channel's early years, it took the title literally, not just with its extensive movie collection, but its library of other special events — boxing, music, comedy and more — that gave subscribers the illusion of having gone out for a night on the town rather than one on their couch. One of the best, and most important, of those music specials, was this reunion of Simon & Garfunkel, attended by 500,000 people, and so popular on record and TV that it inspired the reluctant ex-partners to go on tour together again.
