I've seen a preview of this concert and I have a few impressions I'd like to share.
First of all, I don't recommend the sax mute favored by the British Legion.
It seemed highly acceptable to wear and tear and apparently it's not covered under warranty when the rest of the sax section nibble away at it.
It does seem an effective mute though, as only the audience in the first few rows appeared to have large grins on their faces when the lead tenor started his honking rock sax solo with a pop. I think they must of gotten better sound-bytes than I.
