I only heard this on WKRC in Cincinnati,OH (model for WKRP) in the
early 50's.It went like this:

    There's a New Sound, the newest sound around,
    the newest sound you ever heard.
    Not like a wild boar or a jungle lions roar,
    not like the cry of any bird.
    But,this new sound ......

    I thought for years that Nervous Norvus did this,but it wasn't
    the case I found.

    No one seems to have clue what I'm talking about.
