multicast sparse mode

I've got three routers connected via frame with one hub and two spokes.
They are all running PIM Sparse mode on the cloud and the lan interfaces.
When I ping from a spoke I get a reply from the other two serial nterfaces
but not from the lan interfaces where I have placed the join statement. My
RP is at one of the spokes. Is this what I should be seeing?

Any ideas?
