Edinburgh was fun. Hard work, but fun. Singing with a nice bunch of people is always a good thing, and when we're doing such challenging masterworks as Tallis' Spem in alium (where everyone has to pull their weight: it's for eight choirs of five parts each...) it's good for the brain cells too: certainly better for them than the post-concert social occasions, aided and abetted by Scotland's sane licensing laws — unlike in England, alcohol may be served after 11:00pm.
