There was a club called "Wheelbarrow at 55 Camden High Street, Camden Town, London but it's not there now. Luckily, there are still some images around.
This seems to have been take from a window (bus? another business?):
If anyone comes by who know when it was founded and why it was named "Wheelbarrow," please leave a note! If there was any wheelbarrow art (on signs or menus or whatever) I'd like to see that image, also.
