And you may consider using "debug ip routing" to help along the way and see
if you have recursive routing at all (e.g. you stuck your tunnel destination
network as one of the routes IN bgp).
With recursion though, you'll still get your peers up, then later on you'll
get a hold time expired message and things will fail. That's always
entertaining. (Perhaps not your problem right here, but it sounds as though
you may want to pay attention to it!)
In the beginning you are simply looking for connectivity. And no ACL! :)

First check that R1 & R2 and R2 & R3 have direct connectivity to
each other. Next check that R1 and R3 have connectivity to each other using
the addresses they will source the tunnels from. Establish the tunnel
between them and test connectivity over it. Only once this is all
successful can you then establish the BGP relationship. The neighbor
statement should point to the remote IP address of the tunnel.
Be sure to take next-hop processing into account as well. The goal here is
to make sure that the BGP next hop recourses to the tunnel interface.
If you're still having trouble post your config and show output.
