Slowly going through videos...more to come

Of drumbeats and heartbeats: the sound right at the beginning
Orchestra of People noises: the whole thing?? kind of tough to pick out...there are some great noises in this :)
Chopstick drumming: I suppose at any point he's "drumming"
Rainy day: any part
Peek-a-Boo: giggles at 0:05, 0:12, or 0:15
Are you recording?: about 0:03 (harmonica)
