Never Gonna Give You Up was released by English singer Rick Astley in 1987 as the lead single from his debut album Whenever You Need Somebody, and it became a worldwide number-one hit. Two decades later, the song became the centre of Rickrolling, an internet prank in which a misleading link unexpectedly plays the music video instead of the promised content. The joke spread through forums, social media and video platforms in the late 2000s and never fully faded, because the song is catchy, instantly recognisable and harmless enough to work across generations of online humour.
