In 1969 they created Tommy, the first successful Rock Opera.
They played Woodstock but hated it. Said Entwistle: "Probably the worst ever festival experience we ever had."
Before they were The Who they were The Detours, then The High Numbers.
They started out as a cover band, performing American R&B songs.
Daltrey was kicked out of the band in 1965 after a fight with Moon (Daltrey flushed his drugs down the toilet because he felt it was affecting his performance). Daltrey apologized and 3 days later, they took him back.
They made the Guiness Book of World Records for loudest concert for a show in London on May 31, 1976. The record was beaten several times before Guiness stopped listing it because too many people were losing their hearing.
Moon died on September 7, 1978 after taking a lethal combination of sleeping pills and alcohol. He died in the same apartment in London where Mama Cass Elliott from the Mamas And The Papas died 4 years earlier. The apartment was owned by Harry Nilsson, who let friends stay there when they came to London. After Moon's death, Nilsson never came back.
"Thunderfingers" and "The Ox" were among nicknames given to bassist John Entwistle.
They left their first manager, Pete Meaden, to sign with film directors Kit Lambert and Chris Stamp. Meaden died a few years later of a drug overdose.
Entwistle was found dead in his Las Vegas hotel room on June 27, 2002. The band was to begin a tour the next day, and while they postponed the first dates, The Who did the tour anyway. A coroner's report found that Entwistle was doing cocaine before he died.
On December 3, 1979, 11 people were killed, and dozens of others were injured at the then Riverfront Coliseum in Cincinnati, Ohio, when concert goers were trampled while attempting to enter the arena. Apparently the band members were on stage warming up and people outside waiting thought that they were starting the show. Only a limited amount of doors leading inside the building were opened, prompting a stampede to gain entry. The Who, as well as the coliseum officials, the promoter, and the city were all sued and found liable for the mishap. This ultimately lead to the ban of "Festival Seating" in Cincinnati, which is still in effect to this day. The Who hasn't played in Cincinnati since.
In 1983 Daltrey acted in The BBC's adaptation of Shakespeare's play The Comedy Of Errors. He played twins, both named Drumio, which are servants of another set of twins, both named Antipholus.
In the '70s, they were cited in the Guinness book of world records as the world's loudest band.
