I was going to dedicate the very cosmic tune to you!

Anyway, very generous comments on my singing. I don't think I'm in Steve Kilby's ballpark (yes he's the frontman) but it's very nice of you to say.
You summed up my thoughts on the tempo very well. I do tend to favour the slower tempo, although not as slow as the excellent version Bob posted. I'm not locked into it by any means, I could certainly experiment with quicker versions. "Rousing" people isn't always a bad thing eh! Thanks Pierre for your thoughtful comments.
