I saw him at Warren Place back in July. He's a gorgeous, big horse so my guess is that he won't be seen until the back end of the season. We saw him do a routine canter with two other companions, so he's certainly been in work. Racing Post don't usually add a horse to their database until it receives its first entry, hence why he's not on there yet.
Thanks PN gonna get a piece of A4 and make an actual chart for the Northern Dancer bit so I can see what's going on.
