Lively!
Thank you for such input!

Lemme see, there's also "Doo Wah Diddy Diddy."

Yes, it's how you sing them.

As to the sidetrack: I have for some right several decades used "a capella" interchangeably w/"unaccompanied by an instrument." Other misnomers from my youth: "Natives:" half-dressed black men running single-file through the jungle, ululating and brandishing spears. (Too much 'Ramar'). "Ethnic:" twangy Appalachian singing. "Modal:" no thirds.

Looking forward to checking out these songs, and hearing more suggestions. You've already sent my thoughts down a path or two. (w/o spear)

So is there an e-mail notification of replies, or does one lurk in these threads? (Not a bad thing!)
