I love disco music but I didn’t dance to Chic last Tuesday night. Instead, I watched a YouTube video of (early 80s Belgo-Portugese popstar) Lio’s ‘Sage Comme une Image’ on a disco loop. The music is exotic but fun: a tipsy groove Nile and Bernard would surely dig; Europe via downtown New York and all that. In the vid, Lio applies red lipstick, shimmies, then coyly boozes it up… as some weird dude just kind of hovers.   ‘J’adore cette chanson et le clip est genial.’ ‘Timeless musique!’ ‘Oh those French girls…’ offer some comments. ‘Nice titties’ suggests another, less…
