Dear Anglo,
The one time we recorded something from Britain that didn't have a publisher here we recorded Huw Williams' song "Rosemary's Sister." In that case Dirty Linen Magazine's Paul Hartman got us in touch with the authot, who said to put MCPS after the song in the credits on the recording and then send a check for the standard US rate to his then record company (Steam Pie Records I believe). A few months later he wrote and said he'd gotten the rights back for the song from Steam Pie and to not send more checks. The amount we were sending we in the tens of dollars and I think the bank may have been charging more for the service fee than what the check was worth. Here we have dealt with Harry Fox, but usually try and find the songwriter themselves and see if we can pay directly (I like to know the money gets to who is supposed to get it). Quite a few British publishers do have reciprocal deals with Harry Fox in the US. But there are also surprising gaps in what Fox licenses or doesn't.
