Women didn't want to be on the stage with other women because they didn't want their bodies to be compared. They didn't want another female act opening for them because of this weird competitive and tokenistic attitude.
The hedonistic lifestyle is difficult to achieve when you're still carrying your own gear. Trust me that you don't feel glamorous with a 60-pound amp in your arms it's a lot less sexy than toting a vodka gimlet and impossible to do in heels.
