Narrative:

Clearance was received prior to pushback, copied as the wobun 2G. It was checked in the computer. After liftoff, as we began a right turnout as per the SID. Lhr tower queried our routing. Stating we were to be on the compton 2G. We reversed our turn and received heading information from the tower. We told the controller at that time that we had been cleared the wobun departure. We were then turned over to departure control. We were a 2 man cockpit, flying international. If the compton departure was assigned, neither of us realized it. We had briefed prior to receiving our clearance, as is normal for international flts. Once the clearance was received, it was entered, verified and reviewed.
