I couldn't put it any simpler and clearer than the "wiki" on Pink Floyd.
Not to mention that when you copy and paste wiki links are teleported fully functional!
"Pink Floyd were formed in 1965, and originally consisted of university students Roger Waters, Nick Mason, Richard Wright, and Syd Barrett. The group were a popular fixture on London's underground music scene, and under Barrett's leadership released two charting singles, "Arnold Layne" and "See Emily Play", and a successful debut album, The Piper at the Gates of Dawn. In 1968, guitarist and singer David Gilmour joined the line-up. Barrett was soon removed, due to his increasingly erratic behaviour. Following Barrett's departure, bass player and singer Roger Waters became the band's lyricist and conceptual leader, with Gilmour assuming lead guitar and much of the vocals. With this line-up, Floyd went on to achieve worldwide critical and commercial success with the concept albums The Dark Side of the Moon, Wish You Were Here, Animals, and The Wall."
"The name Pink Floyd is derived from the given names of two blues musicians whose records Barrett had in his collection, Pink Anderson and Floyd Council
The Division Bell is a collaboration of a lyrical think tank including Gilmour, Polly Samson, Richard Wright, and Nick Laird-Clowes. Polly became Polly Gilmour after the album. She is an accredited author on her own merits. "Black Country Girl In Red China" is a memoir written by her mother of her time serving in Mao Zedong's Red Army.

Richard Wright did the lead vocals on the song he wrote on the album "Wearing the Inside Out", his first lead since the '70's. Nick Laird-Clowes is a good friend of Gilmour and has a strong British musical bio.
Nick was in the band "Dream Theatre", but the most interesting info about him was that he went to a monastery in the Himalayas to recover from drug abuse. Must be nice...much better than the Betty Ford Center!
This album had bad reviews when it was released. I believe it to be one of the best and most unappreciated in the Pink Floyd discography.
