Hi Mario,
I am very pleased you liked the song - good that you liked the chord progression - 13ths and 9ths important here as they influence the melody and not just colouration.

With respect to the guitar lead - I did try other instruments but did not like what I did for the solo bit. I think I feel okay with the guitar - most of the time anyway. Jazz guitar is a possibility.

Thanks again for listening and your very kind comments

Jim
