In 1995, Radiohead were on tour, promoting their second album,
The Bends. During soundchecks for shows in Japan, guitarist
Ed O'Brien produced a high-pitched sound by strumming above the
guitar nut. The band developed the sound into a song, "Lucky", which became part of the
set list. Around this time, the producer
Brian Eno asked Radiohead to contribute a song to
The Help Album, a
charity compilation organised by the charity
War Child. The album was to be recorded in a single day, 4 September 1995, and rush-released that week. Radiohead recorded "Lucky" in five hours with engineer
Nigel Godrich, who had assisted producer
John Leckie with
The Bends and produced several Radiohead
B-sides. Yorke later said "Lucky" shaped the nascent sound and mood of
OK Computer. He said: "'Lucky' was indicative of what we wanted to do. It was like the first mark on the wall." ==Release==
