Chas Hardern's narrowboat hire company, in Beeston is what you want. On the Shropshire Union canal, between Nantwich and Chester. Ideal for Shropshire Union, Llangollen, via Middlewich to the Caldon, all sorts of possible routes. Cheaper than a lot of firms, Chas is a genuine canal enthusiast and runs a very fine business. Now I no longer live on a boat, if nostalgia gets too powerful I hire one off Chas and have a little holiday. I can recommend him unreservedly. PM me if you want any furtherinfo/advice.
   By the way, music is to be found readily in Nantwich, Middlewich and Audlem for starters, all close to Chas' yard.
