Irving was so overly protective of Stevie and his cash cow. The strong arm to rehab saved her life but I am referring to his cease and desist letter to David Letterman because he was playing Stevie's I Can't Wait video. I think everyone was overly sensitive because of Stevie's condition at the time but it was beyond ridiculous. David was a fan and promoting the song. But it led to great TV for about a week. Years later when Stevie did do Letterman in 1994 Stevie blamed her "old" management and said she took pleasure at firing them.
If you have not seen it here is Letterman mocking Frontline Management. I love that David just mocked the hell out of Frontline all week for their ridiculous telegram and then lying about sending it. He gives out the address to Frontline on air.
