In the mid or late 70's, I saw a film where a rich reletive dies. Friends and family gather for the reading of the will. The will/fortune has been hidden, and as they try to find it, they one by one begin to die in their attempt. I believe it is loosely based upon the movie "Ten Little Indians"? I'm almost certain that the music for the film was Paul McCartney & Wings, sing "Uncle Albert". I seem to also remember that the ending is when the last person finds the treasure, which is located in the creamatorium, and of course, they don't live to enjoy their find.
Any idea of the name of this film.
