I hope this link will be successful. Go down to: "Music Composed by Lalo Schifrin", and download the "main title". You only need the "Windows media player". If you have Windows 98 or (probably also) Windows 95 then you have that necessary player.
Then you have the music from the serie "Mission impossible". I admit the serie is some kind of hopeless imitation of "James-Bond & his friends" or whatever, but the melody is nice !
