1989-02-xx Mean Fiddler, London, UK
BONG magazine issue #5 reported:
A surprise 'concert' was held at the Mean Fiddler in London in honour of Gerry McKenna who was leaving Mute after working there forever! Artists included Nick Cave ('Leaving On A Jetplane') and 'Duo Diablo' - who looked uncannily like Andy Fletcher and Martin Gore! This odd couple did a foot-stomping rendition of 'Thirty Days' which is apparently a "Chuck Berry classic".
Dave Gahan said in the March 1989 issue of German magazine Spex (translated from German):
"We had a wonderful evening last Friday night, when an employee left the company after eight years and gave a party at the Mean Fiddler, with all of [Mute's] band playing acoustic sets. Nick Cave, Erasure, Wire, us - it went on all night. [Being with Mute] matters a lot - it's like a family."
There are no known photos or recordings of "Duo Diablo"'s performance.
