Robert Plant, the legendary Led Zeppelin frontman, revealed that his favorite song of all time is Mario Lanza's 'Serenade', a romantic and operatic piece with soaring vocal highs. Plant selected this track on BBC Radio 4's Desert Island Discs, where he also shared other significant songs from his life. 'Serenade' is the title track from a 1956 film about a vineyard worker turned operatic tenor, featuring melodramatic and operatic music. Plant's list of eight songs included rock, blues, ska, Indian cinema, and his own collaboration with Alison Krauss, showcasing his diverse musical tastes. Additionally, he chose a book of Anglo-Saxon poetry as his reading material and opted for a wicker basket with homing pigeons as his luxury item for a desert island.
