There is an excellent review of Dope the movie and interview with me by Ian O'Sullivan in this months Shindig, a music magazine published in the UK, and available worldwide. Geno, his music and connections to others on that scene at the time, is mentioned in the article. You can check out Shindig Magazine on the web, although the article itself is available only in print.
"The rarely screened documentary Dope, by husband and wife directorial team Sheldon and Diane Rochlin .... provides what is possibly the closest filmic insight to what life in London in 1967 was like for those on the inner circle of the counter-culture."..Shindig'09
