SWITCHING WORDS IN FILE NAME

I found this answer before but can't find it any longer. I have a file name: "Lance, Gill - Example of name". I want to switch the first two words and rename the file as: "Gill Lance - Example of name". I have many book titles with different authors that I want to change using this method. I remember the solution was based on something like "/2 /1" or something similar to that, but it's been so long since I researched this that I have forgotten what the correct solution is. Thanks for any help.
