I would be seriously tempted by Flower Power if they had dedicated parties say to psychedelia, Pink Floyd, Jimi Hendrix, people I really admire rather than random golden oldie cheese. Maybe some themed event with a film or talk beforehand, something with imagination and effort put in.
This is for me :

I HATE PINK FLOYD
John Lydon was spotted wearing "I Hate Pink Floyd" t-shirt. That day, UK Punk was born.

Jimi Hendrix ? Ok ,so far.
Maybe a Post Punk night would be something good. Mondays , OMD , Cure , DM , Cabaret Voltaire and so on and on. Its danceable and
mass compatible. I would like to hear Echo and the Bunnymen in Ibiza. Good times , this was.
