Answer 2

Syd Barret
As the band became more popular, the stresses of life on the road and a significant intake of psychedelic drugs took their toll on Barrett, whose mental health had been deteriorating for several months. Barrett's strange behaviour has often been attributed to his drug use. In January 1968, guitarist David Gilmour joined the band to carry out Barrett's playing and singing duties, though evidently Jeff Beck was considered.

With Barrett's behaviour becoming less and less predictable, and his almost constant use of LSD, he became very unstable, occasionally staring into space while the rest of the band performed. During some performances, he would just strum one chord for the duration of a concert, or randomly begin detuning his guitar. The band's live shows became increasingly ramshackle until, eventually, the other band members simply stopped taking him to the concerts. The last concert featuring Barrett was on January 20, 1968 on Hastings Pier. It was originally hoped that Barrett would write for the band with Gilmour performing live, but Barrett's increasingly difficult compositions, such as "Have You Got It Yet?", which changed melodies and chord progression with every take, eventually made the rest of the band give up on this arrangement. Once Barrett's departure was formalised in April 1968, producers Jenner and King decided to remain with him, and the six-way Blackhill partnership was dissolved. The band adopted Steve O'Rourke as manager, and he remained with Pink Floyd until his death in 2003.

After recording two solo albums (The Madcap Laughs and Barrett) in 1970 (co-produced by and sometimes featuring Gilmour, Waters and Wright) to moderate success, Barrett went into seclusion. Again going by his given name, Roger, he lived a quiet life in his native Cambridge for more than 35 years. Barrett died at his home on July 7, 2006.

Put me down for GG Allin too. That guy was a trainwreck. Of the living, you gotta believe Axl Rose has completely lost it.
