Ebi - Persian classic

I am not sure if I have presented Googoosh on this blog. I think I must have, but if not, browse wiki and see for yourself, I might post something later. But this time EBI. I think we can compare them. They both left Iran after the Islamic Revolution (correct me if I am wrong), having been very famous there for their music before and then continued to produce music in exile. The video above is a classic, there's also newer stuff on youtube, but I don't like it so much.
However here is another video of a performance of him being a bit older ;) :]
