I'm putting this here so that it doesn't get so easily buried among all the other Proms threads (and can be more conveniently 'bumped' as a reminder).
Many thanks to bluestateprommer who has, for the second year running, entered all the concert details into the forum calendar. The most useful feature is that each concert will be outlined (with a link) in the What's Going On panel at the foot of the homepage one week in advance of the performance. You can browse the headline details in the calendar (calendar link appears at the top of most pages, but not the What's New view) at any time. From the headlines you can click through to the programme details.
So, a choice: Andrew's listings for a detailed one-page view of all concerts and for a printable version; bsp's calendar for the week-ahead reminder and clickable links to separate concerts.
And coming soon: the Concerts 2012 sub-forum. Eine Alpensinfonie has undertaken to start the thread for each concert in standard fashion (as DracoM does each week for Choral Evensong).
Repeated many thanks to all mentioned from a ff!
