Although it's not a recent YouTube posting, I ran across a nice TG4 feature on Mrs. Crotty today. I've done a content search here and don't see any indication that it's been highlighted previously so I'm going to do that now.
The video has some flaws; there's almost four minutes of unrelated content at the start, it ends abruptly during the playing of an Air and the sound seems a little out of sync at times, but all in all I found it to be interesting and worthwhile to watch.
