Would you be willing to do a small favour for love?
A friend has asked if I can help her put a collage together for her wife, if you'd be willing to help out a lovely couple, could you please take a photo of a message with "She loves you, even in (city, country)" with the date (21.03.13) as in the photo attached. Take it at your gig, outside your window, at a local spot or monument.
If you'd be willing to take a minute to help a stranger show their love it would be greatly appreciated
