Narrative:

Both the copilot and I heard bay approach (I don't remember the frequency) say you are following a B747 6 mi ahead to runway 28L then he gave heading 310 degrees intercept the localizer and cross dumba at something. I said to repeat the intersection and he said dumba and I said that's on runway 28R and he said yes you are cleared runway 28R. So we went past the runway 28R localizer till we got it tuned. We think that following B747 to runway 28L led us to mishear or he never gave us runway 28R till the last second.
