February 2015 Song-A-Week 305 The Old Grey Cat.
For some mysterious reason, I could *not* find that page via my usual technique of opening a new tab and going to Google and making a site-specific search:
"old grey cat", site:mandolincafe.com
Usually that works, but sometimes it doesn't. At the time of this writing, Google seems unaware that the page exists. I have no clue why.
However, in those search results I did see a mention of Song-A-Week in a different thread on the main forum, complete with a clicky link, that's how I finally found the 2015 Song-A-Week #305 page.
