I just came across an advertisement for an Irish Music Festival in Southern California called Get Shamrocked from Friday, September 18th to Sunday, September 20th, 2015.
The event info has this to say:
"After two amazing events, Get Shamrocked is now established as a major event on the Celtic music calendar. Gathering the very best Irish and Celtic bands/musicians from across the planet to create a weekend of pure Irish magic. The three day, 16 band line-up has been carefully selected to encompass every aspect of Celtic music with no taste left unsatisfied."
Here's the website: http://getshamrocked.com/index.html
Anyone want to meet up on Friday or Saturday afternoon?
