It was originally intended for Gogo to be found in any of the bars in the World of Ruin disguised as one of the player characters not in the player's active party. Gogo would randomly cycle between the towns based on a timer and if the player managed to speak to him/her with the real character s/he was disguised as, Gogo would reveal him/herself and join the party.

The developers felt the quest was too difficult and changed this for the final version of the game. This could possibly suggest that the Siegfried/Ziegfried imposter was meant to be Gogo during development.
