Once

"Once" is the sixteenth studio album by English rock/folk singer-songwriter and guitarist Roy Harper, released in 1990.
David Gilmour, Kate Bush, Nick Harper and Nigel Mazlyn Jones appear on the album, with Gilmour and Bush both on the title track. Harper supported the release of the album by touring the UK. One of the concerts took place at the Dominion Theatre (a West End theatre on Tottenham Court Road in the London Borough of Camden) and was filmed. The concert took place on the 22 November 1990, the same night Margaret Thatcher announced her resignation as Prime Minister. The concert film was later released as Roy Harper Once - Live.
