Pink Floyd music in Rosencrantz and Guildenstern Are Dead

I saw the end of a movie on TV. In the credits I read this: "The song Seamus taken from the album Meddle performed by Pink Floyd"
The movie was Rosencrantz and Guildenstern Are Dead. I looked for information in IMDB and found this:
The opening song at the beginning of the movie is Pink Floyd's "Seamus" (Meddle, 1971). The version included in the movie is an instrumental version. The album version has vocals. During the theatre company's performance of pseudo-Hamlet, a sound bit from Pink Floyd's "Echoes" (also from Meddle, 1971) can be heard. The sound of the rapier sword is the first note heard in "Echoes".
Have you seen the movie?

i havent seen it, but that version of seamus is in pompeii, its called mademoseille nobs(or something like that).
