I forgot to include this one in my last post:
I believe this clip of the Avco-Embassy logo is from the beginning of Vice Squad. The music heard underneath the logo is unique to the film. My memories of the logo come from VHS and television viewings of Escape From New York and Paradise (1982). The company was bought in 1982 by Norman Lear and re-christened Embassy Pictures. The subsequent blue-backgrounded "E logo" was good, but not up to the high standard of the Avco-Embassy one.
