Tassos Papastamatis (1938 – 2010) was the singer of Greek 60s group Forminx (Vangelis Papathanasiou was the keyboard player and composer).
His deep voice won him the title of the Greek Bing Crosby as it is often mentioned.
Tassos has not a lengthy discography outside the Forminx. A couple of singles, a full cover album and a contribution to George Mouzakis album is all that’s left from this great singer.
