No, he intersperses playing with the verses. It's more than a just a snatch, though, because for the most part he sings whole songs.

Now that you mention it I can't think of anyone singing and playing solo at once. When I saw your post I thought I had one, a version of False Knight On The Road sung to a portion of a reel (Sheehan's, to my ear)but when I looked at the CD in fact there was a singer and a fiddler.
