Little Richard?

Yes, and you can listen to it on youtube too :)

Cruisin' on down Main Street
You're relaxed and feelin' good
Next thing that you know you're seein'
Octopus in the neighborhood!

Surfin' on a sound wave
Swingin' through the stars
Take a left at your intestine
Take your second right past Mars.

On THE MAGIC SCHOOL BUS
Navigate a nostril
Climb on THE MAGIC SCHOOL BUS
Spank a plankton, too
On our Magic School Bus
Raft a river of lava
On THE MAGIC SCHOOL BUS
Such a fine thing to do!

So strap your bones right to the seat
Come on in and don't be shy —
Just to make your day complete
You might get baked into a pie

On THE MAGIC SCHOOL BUS...
Step inside — it's a wilder ride!
Come on — ride on THE MAGIC SCHOOL BUS!

Yeah, you can tell because of that screeching thing in his laugh.
