🕺 Bee Gees' "How Deep Is Your Love" - the 1977 disco ballad that made falsetto cool again! 🎤 This isn't just a love song - it's THE love song that defined the Saturday Night Fever era. Those harmonies? Pure magic. Barry's falsetto? Iconic. Fun fact: The song was written in just one night after the Bee Gees watched the rough cut of Saturday Night Fever. When they sing "How deep is your love?" you can't help but feel the disco fever. The song topped charts worldwide and became one of the most covered songs ever. Plus, that opening piano? Pure disco perfection. ✨💃
