Judas Priest frontman Rob Halford has led tributes to the late AC/DC singer Bon Scott, marking what would have been Scott's 80th birthday on 9 July. Halford shared a video message on YouTube celebrating Scott as "far more than a rock singer" and "a free spirit that could never be contained", while fans across the rock community echoed praise for a performer many regard as one of the greatest frontmen in rock and roll history. The tributes underline Scott's enduring influence nearly five decades after his death.

Scott died in February 1980, aged 33, after being found unresponsive and rushed to King's College Hospital in Camberwell, where he was pronounced dead on arrival from acute alcohol poisoning. His final album with AC/DC was 1979's Highway to Hell, the band's sixth studio record, which reached the top 20 of the US Billboard 200; the group subsequently continued with new singer Brian Johnson. In his tribute, Halford praised Scott's "rare gift" and a voice that "carried mischief, grit, humor, and honesty", a sentiment reinforced by fans who filled the comments hailing him as the "greatest of all time".
