Yeah they were pretty f'ed up back in the day. About 10 yrs ago I saw Marshall Tucker band. Doug Gray was so effing druck he couldn't remember all the lyrics to Heard it in a Love Song. He held the mic out to the audience for about 3 mins having then sing. Later he was off tempo. About 4 yrs later they were at a festival I was at and he was so much better. He seemed totally sober.
