Thanks for all the quick replies
As this is a last minute job, I think the most feasable method will be to have the small MIC inside the earcup of one of the headsets. I actually have one of those that are designed to clip on your shirt (the kind you see on TV) and hopefully, the jack will match that of the recorder.
Thanks again - and I shall let you know how I get on, and if the vid aint too big, I could post it up.........
