Hub & Spoke Multicast problem

Hello everyone,
 
Please could you help me with a multicast problem I have. Here's the
topology:

                        Hub
                     / \
                    / \
                Spoke1 Spoke2

I want to use a static RP (Spoke1 Lo0) for all groups, and join a group
(233.1.1.1) on Spoke2/Lo0. I do not want to use sub-interfaces on the serial
ints.

When I configure this, I cannot ping 233.1.1.1 from Spoke2.

Below are my configs:

Any ideas? I don't need a tunnel between spokes if I'm using nbma mode do i?
Many thanks,

Peter
