Hi Barry,
Am hoping to make it across for that early Sat slot of yours too, looking forward to meeting you.

And hi GeoffLawes, I've noticed that same lack of precise information too, though the Events Schedule on the website itself is pretty detailed as far as it goes. I may be wrong, but it looks very much as though the festival is modelled on the old Lancaster Maritime Festival scenario, viz. all the pub/club sessions would appear to be just a succession of booked-guest spots - except that there is one planned two-hour singaround on the Sat teatime (and even that is hosted by a number of booked guests). Which is a bit of a bummer for those of us non-booked-guests who would like more than just one meagre chance to sing during the festival!
Unless someone who's been to SeaFest before knows different...?
