Brian May in Mad Max movie credits?

I meant to post this recently.

When i was watching the original MAD MAX movie starring Mel Gibson,I saw in the opening film credits that it said that Brian May composed the music.

Now,is this true or is this another composer by the same name,cause I don't really recall anything in Brian's credits doing the music for the fist(and best.)MM film.

another composer same name

Really? Man,I shoulda known.

Thanks for clearing that up teleman,appreciate it.
