Looking for Authentic Mangas or Rebetis

[Magkisa83]

Hope this category is ok. If not, feel free to change it.

Geia sas. It may sound strange, but one of my biggest dreams is to meet a genuine mangas or rebetis. I've been at this for five years all over the place with no luck. I'm hoping someone here can help me. I know that he might not remember much and may not be in good health, but I would still love to meet him, or at least to talk with him, whomever he may be. Anyway, here are the criteria in an outline.
*Needs to be 80 and up. (unless he's a descendent or not a mangas but someone who knew one)
*Needs to have lived in Piraeus in the 30's and/or 40's.
*Needs to have some idea of the teke, mavro etc, though that should be obvious if he's authentic.
Plus if he knew some of the greats, can speak koutsavakika (mangiko), and plays bouzouki. However, doesn't need to be into the music, just the life.
Double plus if he can speak English. (I'm still learning Greek but will have a translator if given advanced notice.).
*Magkises and rebetises welcomed!
I'm totally blind but will arrange for transportation if he's in/near New Jersey or New York. If he's in Greece or another country, I'm willing to pay for international calls.
Feel free to contact me here, by private message or on any messengers we have in common. Sas efharisto.
