Heres a more serious Victor Borge playing Claude Debussy's "Clair de Lune," from Suite bergamasque. This isn't the original composition, he seems to add a few notes here and there, maybe for resonance or added harmony.. who knows. Either way, its Victor Borge, one of the 20th Centuries few true piano geniuses.
this piece was composed in 1890.
(forgive the quality, the video is old and he's playing a Bosendorfer (zing)) :D
