Well I know most of the Shadows older stuff but certainly have never heard this one before.
I think you've captured the shadows style pretty well. Overall this is nicely done, but I think it could be improved.
The organ sound you start with is tonally very close to the guitar, and, to me, seems to mask it a bit in places. Later on when you drop that, the guitar seems much clearer.
I think you are possibly paying the guitar too carefully, which tends to stiffen up your playing.
Thanks for sharing with us - and proving I don't know as much about one of my favourite bands as I thought
