Musical guest?

im trying to remember a musical guest. i think it was either on saturday night live or letterman. and its just a girl singing and a guy on a piano playing like 4 notes the whole song. and i think the girl wore like a really colorful dress. does anyone know who it was or what song it was?
ok im not really sure cuz ive never played piano but i think it goes kinda like: aa, gg, ee ,ff. for most of the song and again yes its played on leyboard. try looking up a virtual piano on google so you know what i mean

I think you were watching Conan and it was Lisa Hannigan. Damien Rice was on the piano. The song was « 9 Crimes »
Is this it?
