It was very generous of Maurice Leyden to give the song to Jane Cassidy, considering she's his wife!

I've been assured by a McCall PhD student that McCall didn't write "Henry Joy McCracken". I tend to agree. It's a completely different, earlier style of language, mood and atmosphere, which McCall, smart tho he was , couldn't emulate. Drennan? I don't think so. The good doctor was quite careful to document his writings (songs, poems,letters). I think it was written by "anon".
