Good question Merv, I think my show was quite different from what others would have done with a psychedelic special as they would likely have been trying to define psychedelic as a genre and all the tracks would likely have been drawn from the time period 1966 to 1968. What I was trying to do was a bit different, I'm not trying to define a genre but to explore an imaginative area. One of the obvious issues that comes up is what relationship does it have to drug use, is it about drugs? I'd say no it isn't about drugs, but the experience of taking LSD was certainly an inspiration to this music, they were trying to artistically create an experience from Ichycoo Park expressed "It's all too beautiful" or from I am the Walrus "I am he as you are he as you are me, And we are all together". I personally think that it is better to experience these states without drugs and absorption in the music can help us to do so. Both the music and the lyrics should express something of a visionary quality. The article that inspired my psychedelic selection included A Day in the Life, which I think has psychedelic elements, but the reading the newspaper about the death in a car crash, has a vibe of resignation and world wariness that isn't psychedelic to me.
I was trying to make the show as a whole a psychedelic experience, rather than be about the psychedelic genre.
I can see the connection between the Steve Hillage track and Genesis and Rush sonically, but it's unlikely I would have used any of their work, you can experience something of the same sense of absorption in their music, but they lack the spiritual intent, I don't see them as psychedelic, whereas I think there is something fundamentally psychedelic about Yes' music.
