Pedlars licences will not be free so even if the Morris teams did obtain them it would probably be self defeating vis a vis income from CDs.

But of course they don't need collecting licences because they are not collecting but busking. In other words providing an entertainment, for which the people being entertained can show their appreciation if they wish, and not just rattling a tin which to my mind has always been an upmarket way of begging.
