I do wish that I'd been a little more selective in the songs that I learned. At my advanced age, it is very hard to learn a completely new song, possibly because the space in my swede dedicated to lyrics is full. It seems that if I force a new one in, an old one fades away, and my taste has changed somewhat. But it is hard to do.
Ah, but you can't put a young head on old shoulders either, can you!
