I'm trying to compile a list of people who haven't recorded a version of Lugubrious Lenny Cohen's 'Hallelujah', but it's tough. So far I've come up with:
preposterously diminished dart-chucker Andy Fordham;
the late Kathy Staff off of Last of the Summer Wine (who did record a ska-tinged version of Cohen's 'Paper Thin Hotel' in 1979);
that brilliant bloke who threw his shoes at Dubya;
the Ood, or at least one of them;
and former union boss and transcendent erotic icon Rodney "Would lady comrades please keep their knickers on until composite 11 has been debated" Bickerstaffe.
I'm pretty sure that's it. Unless you can think of any more...
