Wow 90 minutes in and sorted. If I can reply in reverse order:
Thanks for the link Tony. I recognised the song after it was about halfway through (that forgettable) I can recall that the 1st time I heard it, without knowing the title, and wondered why he was singing about Will?
I don't wanna stand still, I just wanna free Will
To the other Tony - I think my main concern would be if there are still a lot of 'oldies' around because 7 dance tracks in a row and I suspect Granny will be up belting me with her handbag

so I'll decide on the fly.
Brian - I was under the impression that, after the other tracks she had listed, it would be of a similar ilk but I think Tony may have located the one (I'll give her a call later & check). I agree about the track by Duke - kinda reminds me of summer too, might just fit that in.
Stephen NI - When I tried the complete set it lasted for about 20 mins so I thought as both Saltwater & Dancing in the Dark have slow & recognisable starts which normally work well I put them 1st for a split set. Thanks for the extra suggestions too, I'll have those ready.
Chris S - If circumstances permit I'll do it as one. The reason I split them at that point was because Dancing In The Dark is normally a 'Get Em On Their Feet' tune (here anyway) from the moment the 1st few bars are played.
Job's a good 'un
