Never Gonna Give You Up was released by British singer Rick Astley in 1987 and became a number one hit in more than twenty countries. From 2007 the song found a second life through rickrolling, where a misleading link or video unexpectedly leads to its music video. Instrumental covers on piano, recorder and flute became a popular softer variant online, letting creators hide the melody in vlogs, tutorials and presentations before the audience notices the familiar tune and realises they have been rickrolled again.
