Well-known YouTube musician Bill Wurtz made this video where he takes a snippet of Paul McCartney talking in an interview and plays chords under it to match the pitches at which he's talking. An enterprising youtubesman named Jonah Myers then took a video of Bill Wurtz talking in an interview and played chords under it to match the pitches at which he was talking. Quite an entertaining idea. Jonah Myers's Youtube channel has lots of excellent original music on it as well -- he hasn't uploaded in a while, but give it a listen!!

[Update: as of 2023/12/14, the channel and its videos appear to be down, and the videos aren't archived on wayback, so I've tagged this #dead-link. :( Hopefully they will make a return at some point...]
