The Glasgow hooker feared his pro-rugby days were over when he was released by Edinburgh after an injury-affected spell, only to be invited along to Scotstoun by Gregor Townsend. Fraser has made the most of the opportunity - going on to win a PRO12 winner's medal and play for Scotland in a World Cup and Six Nations.
And nothing would delight Fraser more than to get the better of his old team in tomorrow's PRO12 derby at Scotstoun and give his head coach a winning send-off - Gregor will take over as national boss after the 1872 Cup match.
Fraser told the media ahead of the match: "There is an extra edge to this match for me. grew up in Edinburgh. I went to school in Edinburgh. My club as a kid was Edinburgh.
"But I would be lying if I said that I have fond memories of leaving Edinburgh.
"I do have fond feelings about the way Gregor, the other coaches and the players welcomed me to Glasgow. I now love everything about the Warriors and the whole culture here."
Fraser added: "When I think back to what happened to me at Edinburgh, there is always going to be a bit of rivalry.
"Like others, I had some difficult times through there and found it tough in the latter years.
"Gregor saved my career by taking me to Glasgow and I have been rejuvenated.
"I can't stress enough how thankful I am to him. As soon as I arrived here I knew I was in a comfortable environment - and somewhere I wanted to be."
