Mungo Jerry?

There's a sample sound that's been featured on numerous hip-hop tracks...for example, the one I can think of off the top of my head is from Welcome 2 Detroit, "Featuring Phat Kat". It's that little vocal sample, "UGHH". Is it taken from Mungo Jerry's "In the Summertime"?

Nope....

It's Rufus Thomas "Do The Funky penguin"

A Breakbeat CLASSIC!
