I wasn't at that session, but on Thursday I did get a call in the session. It is all about intrusion, I have the phone on vibrate and ignore the call, leaving at a suitable juncture to go outisde etc to return the call. This is to facilitate the best enjoyment of the festival for those I am with. As far as I can tell it has never intruded.

I am sure I am typical, but not everyone is.

The only time I let the ringtones loose is to demonstrate what Horses Brawle (in the key of GG) sounds like or La Morresque. Most musicians know the tune, but not always the name.

Phones (mobile/cell) have positive uses, sometimes.
