Robby,
I'm sat here with goosebumps all over listening to this. I know what you and your son have gone through over the years and to hear you both working together is really something special indeed.
I bet this made you so very proud and I'm hoping this could be the start of a very wonderful collaboration.
You say this isn't your best, well I have to disagree with you my friend.
I enjoyed everything about this and I thank you very much for sharing.
Hopefully I won't have to wait long for another song from Robby and son.
Mark.
