Six Pack is a 1982 American comedy-drama film directed by Daniel Petrie, and stars Kenny Rogers, Diane Lane, Erin Gray, Anthony Michael Hall and Barry Corbin.
The 25th Annual TV Week Logie Awards was held on Friday 22 April 1983 at the Wentworth Regent Hotel in Melbourne, and broadcast on Network Ten.

 Guests included Dennis Waterman, Pamela Stephenson, Gregory Harrison, David Ogden Stiers, Jack Klugman, Mike Farrell, Erin Gray, Chuck Norris, Peter Davison, Priscilla Presley, Gordon Jackson, Shelley Fabares, Kate Jackson, Stephen Collins and Graham Kennedy.
"Doll on a Music Box" is a song originally from the 1968 musical film, "Chitty Chitty Bang Bang".
 It was subsequently performed in the 2002/2005 stage musical "Chitty Chitty Bang Bang" as well.
 It is both a musical and lyrical counterpoint to the more free flowing, legato song, "Truly Scrumptious".
 In the song, Truly is disguised as a wind up music box doll, metaphorically and actually on a pedestal.
 In the song, Truly sings about herself and her rigid nature, all behind the mask of the "doll" she is portraying.
 In the motion picture the part of Truly was played by actress Sally Ann Howes.
 In the stage musical version, the part was re-created by 19-year-old London actress, Emma Williams.
 In 2005, the Broadway "Truly" was portrayed by actress Erin Dilly, who was nominated for a Tony Award that year for the role.
Evening in Byzantium is a 1978 two-part, four-hour made-for-television film produced by Glen A. Larson Productions and Universal Television, and directed by Jerry London, about the Cannes Film Festival being overtaken by terrorists.

 The film is loosely based on the novel of the same name by Irwin Shaw.
