Please can anyone help with last one: Bore to tears. Answer is a river, anywhere in the world.The only thing I can think of is Wear, but I don't think it's right.
How about Severn? It has the Severn Bore (sort of tidal wave) and in the 70's The Gumbay Dance Band had a hit with '7 Tears' which sounds like Severn...or is this too tenuous?.
Number of letters isn't given unfortunately. Thanks for suggestions - it could probably be any of them. So far, I haven't found any answer that seems absolutely definite. Will have to plump for one and send off entry!
