Maybe you typed in an extra space (Mick Hanly) by accident or something like that. The search works just the same for songwriters as for any other name or word. And sometimes it goes off the boil and won't work, like the rest oif us.

Often the names of writers aren't in the DT, because they weren't included when the song was posted, maybe because the person doing it didn't know - there's a standing request for people who notice that kind of thing to send in the information so it can be added.)
