Fun is a good adjective for the album, @reubent, one I should have emphasized. Seen performing live (as I have, in the bands of both Dave Edmunds and Nick Lowe), he is DEFINITELY having a good time on stage. He appears to enjoy drink, but not to the point of making his playing sloppy.
I also failed to mention that Geraint is a multi-instrumentalist, something I really respect. He lists the other musicians who played on each song on the album, so the rest are played by he. Not just guitar, but apparently drums. The small list of others who can or have done that is pretty small: Richard Manuel (The Band, of course, a GREAT drummer), Dave Edmunds on his first two albums, Stevie Wonder, John Fogerty on his first solo album (under the name The Blue Ridge Rangers, a "Hard" Country album), Todd Rundgren, a few others who are not coming to mind. The master multi-instrumentalist in my book was Levon Helm: beside being one of the greatest drummers of all-time, he played guitar, mandolin, harmonica, Jew's harp, and sang like a bird.
