Che lovers!

Today I need your help!!!
Over the past weeks, almost month I constantly read something about Che.
First his biography by Jon Lee Anderson (which I thought was real good) and several books written by Che himself.

And now I would like to talk to some people who actually got to know Che. Who fought or works with him or could call themself a friend.

Maybe some of you know the author Gnther Schaaf. Im trying to get in contact with him, and so far it doesnt look bad. Gnther Schaaf worked with Che for a couple of years in Cuba. Mr Schaaf was sent by the GDR to Cuba but you can read more about his relations in his book Meetings and Discussions 1961-1964 in Cuba (?).
(The German title is Begegnungen und Gesprche 1961-1964 in Kuba).

So if anyone out there might could help me? Thatd be too awesome Im grateful for all you help!

By the way, does anyone here know if there exist so called work and travel programmes in Cuba? Or other ways to spent at least 1 year there (where I could work for my hosting and food). ???!!!
