From Wikipedia:
The Return of the Pink Panther is a 1975 comedy film and the fourth film in The Pink Panther series. The film stars Peter Sellers returning to the role of Inspector Clouseau for the first time since A Shot in the Dark (1964), after having declined to reprise the role in Inspector Clouseau (1968). The film was a commercial hit and revived the previously dormant series and with it Peter Sellers’ career.
A soundtrack album with Henry Mancini’s score for the film was released by RCA Records. Richard Williams designed the cover, using a chromatic setting of Tonight for the typography. Tonight is an all-caps version of Eurostile Black with added shadow. Its letterforms are filled with dots, emulating lightbulb lettering.
