The Show Opening is the best ever. And the theme music IMHO is one of the best scores for a TV show ever done.
Opening and Closing credits (some of the best ever in television history) https://www.youtube.com/watch?v=dWTdmwwK-ME
Music: https://www.youtube.com/watch?v=6Sy_MXRta8o This video has a comparison of the original vs better credits (starting at 5:35) and some background to the music: https://www.youtube.com/watch?v=Vp53tkVtlhA
I have the CD soundtracks that get some play every so often.
