I think the nearest one to Skipton and Harrogate is the Embsay and Bolton Abbey line - which is shorter than the NYMR. There is also the Keighley and Worth Valley, but it is a bit nearer Leeds, I think, than Harrogate.

I will let you know about the speaker - I'm not even sure yet who it is. It must be a bit repetitive for whoever it is as there are about ten ceremonies over two days!
