Nico, Bill Mitchell was a legend. My father was a trainer at South at the same time and every Sunday morning at South's ground both Bill Mitchell and my father whose name was also Bill would be giving rub downs to footballers from not just South but from everyone, they also had a lot of TV stars come through as well.
Because they didn't have a licence to practice they often got raided by the police.
Henry Bolte was premier at the time and would always complain about a sore neck to his doctors, he was told to go to Bill Mitchell and he would fix him up, but because he wasn't licenced he wouldn't go, eventually he went to see Bill, weeks later when he was fixed they were granted a licence.
As kids my brother and I use to sit on the trainers bench while the games were on, got to know lots of players during the 60's and early 70's
