Looking for AT&T predefined ringtone "Swan" from around 2009

[RealBlackStuff]

I have a Pantech Breeze C520, originally sold by AT&T, since unlocked.
This cell came with predefined ringtones, one of them "Swan".
Is there any way to copy/extract that "Swan" ringtone?
Or does anyone have it?
There are gazillions of "Swan"-like/related songs on the web, but none of them what I'm looking for.

I have a USB-reader for SIM-cards, but that ringtone is not on the SIM-card, and I can't copy it onto it either.
I do not have a USB-cable for this phone.
It's probably part of the preloaded software on it, which has Version: IQUS04132009
