Veteran rock band Pink Floyd took their record company EMI to court in London Tuesday in a row over online royalty payments.
Pink Floyd signed with EMI in 1967 and their albums include "Dark Side Of The Moon", one of the top-sellers of all time.
Their lawyer Robert Howe told the High Court that the dispute was about online royalties and whether EMI was entitled to sell individual tracks "otherwise than in the original configuration of the Pink Floyd albums".
He argued that this was "expressly prohibited" under their contract but said EMI argued that the clause did not apply to online sales. The case is likely to run for days.
Pink Floyd found fame with their brand of progressive rock in the late 1960s and early 1970s, hitting the global big-time with 1997's "Dark Side of the Moon", followed by "Wish You Were Here", "Animals" and 1979's "The Wall".
Relations between the original members of the band were strained in recent years but they reunited for the giant Live 8 concert in London's Hyde Park in 2005. Keyboard player Richard Wright died of cancer in 2008 aged 65.
