Sorry folks - been on the go a lot, last few months. Apart from a family bereavement we've had a few 'hassles'!
As well, my ABI, tends to "fold time" so to speak, in that, something I think I have told myself to do, 'drops out' and resurfaces a day or so later in the mental inbox only for me to find that the 'day or so, is actually 6 months or so! Short Term memory Loss is a bitch!
I believe the version I have been listening to is sung by ?Les Wilson??

I really appreciate your help, so if you can work out the chords and place them for me, I'd appreciate it:

I tend to transcript my songs thus: (Wild Mountain Thyme)

       G       C          G
O the summer time has come

          C                   G
And the trees are sweetly bloomin'
