Ok, i recorded a quick Version too
I thought that i will have to try it many times for a version good enough for a public audience
and I was so surprised that I made so few mistakes in the first try, that I forget to repeat the second part (that one which isn’t in your version) so from 24 sec to 30 sec it should be repeated, but I am happy that it was so easy, and so I am presenting my first recorded version of Katie Bairdie on the whistle
I played it in the speed like on the CD coming with that tutorial I use
Dont be surprised about the sound of my whistle, cause I didn’t want to wake up the neighbourgs (its nearly 4 am here),
I played my whistle in its silent-mode (you can do that with the parks whistle but than it get very breathy, well i even like it but its maybe strange for your ears)
please be critiqual with me but not with the whistle cause its great, i just cant play it well 
After recording I did listen to all our 3 versions and I noticed that your 2 versions are even different from the notes
Here are the links for all our versions for easy comparing

the extra part beginns at sec24 (i dont know if its suposed to be there or not in original)
looks like JLeo and i Play it different that Marco
it seems he play the second sequence wrong (e,f,g,e,f,g, instead of … e,f,g,(f),e,f,g
… thats what i did mean Marco (in your thread https://forums.chiffandfipple.com/t/my-tin-whistle-learning-youtube-channel/82612/8), you run to fast through the lessons, you should take time to master each lesson and dont forget some notes by hurying 
but hey, i made some errors too, thats why i said, i dont feel good enough for public recordings yet and id prefere to exercise a while more and than present a good recording
anyway, this way now we can show our develloping better 
Also I have written down my notes and have marked red what marco plays different and blue is the extra part which isnt in your tutorial, this way its maybe easier to see what i mean
Here it is

well now its time for bed I guess … or should i go into complete silent-mode and whistle a bit? 
p.s. i wonder if ever some beginnes have talked so much about their first tunes, in this forum, as we do, … anyway this way we learn and develop
