Narrative:
During preparation for departure from dfw; I fell victim to a classic case of pattern interruption. There were numerous distractions in the cockpit when I pulled up the clearance. I failed to notice the amendment to use another SID. Unfortunately; this new SID has the same initial waypoints as the original SID. Checking in with the ground controller and giving him our runway and initial waypoint did nothing to help us catch our error. Fortunately; before we departed from the ground track that is common to both sids; we were given a direct routing to a waypoint down the road. It was at that point that we realized our mistake.supplemental information from acn 694969: the verification process is useless when more than one RNAV departure uses the same first fix. The RNAV departure verification should include runway; assigned departure; and first fix.
