"Dangermen wanted" - bizarre job advert requires acrobatics and cave singing

A company in Wales has advertised for a rather unusual position, which requires applicants to have a head for heights and also be able to sing a cappella.

Llechwedd Slate Caverns in Blaenau Ffestiniog asks for candidates who are “physically fit and strong and able to work in semi-darkness.” The role, which is listed by JW Graves, also wants jobseekers that are bilingual in Welsh and English, good with acrobatics and balancing skills.
