Plácido Domingo & Rolando Villazón sing John Denver's "Perhaps Love" on Friday, June 27, 2008 at Vienna's Schloss Schönbrunn.
Now how about Plácido Domingo and the main man himself, John Denver, in a 1983 duet?
I dunno...this song sounds like the cheesy accompaniment to super-soft pr0n from the 1970s or something.
