<Abdul Abulbul Amir
Oh my goodness, I remember this song from Captain Kangaroo. Every now and then I try to look it up, but could never get the name right.
I found 3 versions on iTunes. Thanks for taking me down memory lane!
I thought it was Abdul the Bulbul Emir. But I got Ivan Skavinsky Skavar right, which was enough. It turns out that googling "and quite unaccustomed to fear" or "to harass the foe from the rear" is enough. Google is a useful tool even if the people who run the company are evil.
