Just looked at Masato's posts. The first listed, (Masato as Guest), was on "Froggy Went A-Courtin'," which coincidentally, is the subject of a current thread. "Scandalize My Name" and "Old Lang Syne" also were in the first five posts and are already an indication of the variety.
Look at the search results; is there anyone interested in songs and song history that he hasn't helped?
