Fascinating!

As a non-native English speaker, yet one who's been in North America and dreaming in English for 2+ decades, Ooboontoo was the one and only pronunciation that came to my mind (I suppose because it's a fairly phonetic interpretation).

To me, "You-Ban-Too" is a completely "you have to squint and tilt your head and really want to see it" pronunciation/interpretation :->

It's partly because of the flattening of certain vowels that happens in Am English. Like how con is similar to Kahn in Am English, bun has a little ah to its uh. Hence u (you) bun (bahn) tu (Too).
