OK, so I watched The Big Lebowski today Apprarently Tara Reid as Bunny Lebowski sings a song that I have now forgotten. Anyone help out with this one?

"Canadian Bacon": a failed try of "Born in the USA" sung by John Candy and the two other guys.

In "Click" a guy pulls up next to Adam Sandler in a Covette, over-enthusiastically singing "Working for the Weekend"

In "Bananes Mécaniques" , the girls sings a "Chanson paillarde" in the Citroen 11:

Oui, je sens bien Adrien
Ce n'est plus ton p'tit doigt qui m'chatouille
J'sens ton nombril contre le mien
Et la chaleur de tes couilles

In the Almodovar film "Atame" (Attache-moi) ... at the end, Antonio Banderas, Victoria Abril and Loles Leon are into a Seat Ibiza and sing a famous song but I cannot tell what title it is

Here are a couple more . . .

Updating the "American Beauty" entry

American Beauty - Annette Benning - Don't Rain on My Parade - Bobby Darin

Defending Your Life - Albert Brooks - Barbara Streisand - ?
Reality Bites - Jeanne Garafalo/Winona Ryder - ? - Tempted by the Fruit of Another
Godzilla - Matthew Broderick - Fred Astaire - Singin' in the Rain

Also, I just watched "Meet the Parents" and that entry should be removed as Stiller and Deniro are driving in the car but all Deniro says is "Puff" one time and then launches into a conversation, so it's not really singing.

Maximum Overdrive> The Bible salesman is singing some song (it was: One step at a time sweet Jesus, thats all I'm asking you.....).
