Jean-Francois Dor, one of our members (who's attended a few meets) is inviting us along with others from the GPN (Gay Professional Network (http://www.theggpn.com/)) & GBA (Gay Business Association (http://www.gba.org.uk/)) to a private viewing of the Pink Singers exhibiton, Europe's longest running LGBT Choir. Its their 30th anniversary this year.
Find out more and RSVP at http://pinksingers.eventbrite.com/ - RSVPing here on meetup will NOT count (though it will show others from the group who else is going, so I encourage you to click yes here too if you sign up). If you haven't used eventbrite before, it just manages the ticketing for many events (both paid and free).
The location is nearest Blackfriars and Temple tube stations, or City Thameslink train station (the eventbrite link just mentioned has a link to the google map location).
More info from Jean-Francois...
