by the way - I have also signed 'Over the Rainbow' and 'Jingle bells'
and a song called 'Magic Penny' and many others - mostly religious ones for assemblies but I signed 'ten pints of tetleys' at Whitby's Moor and Coast festival and translated Lancashire Sid's 'Pratty Pie' which is a dialect poem. Some things just translate better than others
I think my favourite song in sign is 'From a distance'
