How about "debug ip bgp (neighbor ip address)" or "debug ip bgp events".
But you don't need to do that even.
Emanon-R5#sh run | b router bgp
router bgp 5
no synchronization
bgp log-neighbor-changes
network 10.5.5.0 mask 255.255.255.0
network 172.17.155.0 mask 255.255.255.0
neighbor 172.17.1.4 remote-as 4
neighbor 172.17.1.4 ebgp-multihop 255
neighbor 172.17.155.1 remote-as 555
no auto-summary
!
Emanon-R5(config)#router bgp 5
Emanon-R5(config-router)#no neighbor 172.17.155.1 remote-as 555
Emanon-R5(config-router)#
40w6d: %BGP-5-ADJCHANGE: neighbor 172.17.155.1 Down Neighbor deleted
Emanon-R5(config-router)#neighbor 172.17.155.1 remote-as 100
40w6d: %BGP-3-NOTIFICATION: sent to neighbor 172.17.155.1 2/2 (peer in wrong
AS) 2 bytes 022B
Emanon-R5(config-router)# FFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFF 002D 0104

Emanon-R5(config-router)#
The "022B" in hex is "555" in decimal which is the original AS number that I
had configured.
Emanon-R5(config-router)#no neighbor 172.17.155.1 remote-as 100
Emanon-R5(config-router)#neighbor 172.17.155.1 remote-as 555
Emanon-R5(config-router)#
40w6d: %BGP-5-ADJCHANGE: neighbor 172.17.155.1 Up
Emanon-R5(config-router)#
