Narrative:

On arrival at xyz did not hear tower give clearance to land. Queried controller all the way down final at 150 ft executed go around as tower cleared some other aircraft to land on runway 8. Landed uneventfully. Controller appeared to be task saturated -- which can be expected in the area. On discussions with the tower supervisor, he mentioned that he thought landing clearance was given and that he would review tapes. He offered his apologies for the misunderstanding.
