Wellies - check. Wet wipes - check. Flag - check. Full-length black eveningwear - check, check, check!
On Saturday 29 June Voce perform live on the Pyramid Stage at Glastonbury Festival with headliners the Rolling Stones. Once again we'll be joined by choral scholars from the London Youth Choir as we provide choral backing to one of the Stones' greatest hits.
To find out which one, follow us on Twitter, keep an eye on the BBC's live streams, or maybe even catch us on TV. We'll update the Voce blog with the full story and all the backstage gossip when - if - we get back to London.
Are you at Glastonbury Festival? Come and say hi - we're @vocechoir on Twitter if you can't see our flag. Couldn't get Glasto tickets this year? Catch us at the Stones' Hyde Park gigs on 6 or 13 July.
