Yes I thought they were very well done as well and there's others he's covered recently on his YT channel that's quite good as well.
TBH I've never listened to much Green Day over the years myself and still don't and I don't know why since I do quite enjoy listening to some of their music. I think I've only ever bought their Dookie album likely for the songs Basket Case and When I come around. A couple of more tunes off the top of my head that I enjoyed from their other albums over the years were Good Riddance and Boulevard of Broken Dreams.
Yes I do have a broad taste in music but it's mostly classic rock with some Irish/Newfoundland style music thrown in but I can listen to just about anything. The past couple of years I've since ventured more into the southern rock/bluesy type music from listening to Warren Haynes and the bands he's been in more and more and also the Tedeschi Trucks Band which has become a favorite of mine.
The tune you posted is quite good as well. I had never heard of Ralph McTell but will check out more of his songs later. I have listened to Nancy Griffith before and might he have that album here somewhere. I've heard the Clare to Here a few times being sung by others.
Here's another of Billie Joe Armstrong's recent covers. Covering Eric Carmen's That's Rock and Roll. Very good song and quite well done IMO. I don't care for Shaun Cassidy's version
and prefer Eric Carmen's instead and now this recent cover by BJA.
