Mary Poppins (film): Mary Poppins is a 1964 American musical-fantasy film directed by Robert Stevenson and produced by Walt Disney, with songs written and composed by the Sherman Brothers.  The screenplay is by Bill Walsh and Don DaGradi, loosely based on P. L. Travers' book series "Mary Poppins".  The film, which combines live-action and animation, stars Julie Andrews in the role of Mary Poppins who visits a dysfunctional family in London and employs her unique brand of lifestyle to improve the family's dynamic.  Dick Van Dyke, David Tomlinson, and Glynis Johns are featured in supporting roles.  The film was shot entirely at the Walt Disney Studios in Burbank, California using painted London background scenes.

I Love to Laugh: "I Love to Laugh", also called "We Love to Laugh", is a song from Walt Disney's film "Mary Poppins".  It was composed by Richard M. Sherman and Robert B. Sherman.  The song is sung in the film by "Uncle Albert" (Ed Wynn), and "Bert" (Dick Van Dyke) as they levitate uncontrollably toward the ceiling, eventually joined by Mary Poppins (Julie Andrews) herself.  The premise of the scene, that laughter and happiness cause Uncle Albert (and like-minded visitors) to float into the air, can be seen as a metaphor for the way laughter can "lighten" a mood.  (Compare Peter Pan's flight power, which is also powered by happy thoughts.)  Conversely, thinking of something sad literally brings Albert and his visitors "down to earth" again.  The song states a case strongly in favor of laughter, even if Mary Poppins appears to disapprove of Uncle Albert's behavior, especially since it not only complicates the task of getting Albert down, but the infectious mood sends Bert and the Banks children into the air as well.

Step in Time: "Step In Time" is a song and dance number from Walt Disney's 1964 film "Mary Poppins", and it is composed by Richard M. Sherman and Robert B. Sherman.  The choreography for this song was provided by Marc Breaux and Dee Dee Wood.  It is sung by Bert, the chimney sweep (Dick Van Dyke) and the other chimney sweeps on the rooftops of London.  In the first part of the song, the lines he says in the verses are "Kick your knees up", "'Round the chimney", "Flap like a birdie", "Up on the railing", "Over the rooftops" and "Link your elbows" followed by an interlude.  The interlude continues with Bert, Mary Poppins, Michael, Jane and all the chimney sweepers dancing around the rooftops and as Admiral Boom looks at them with the telescope, he thinks that they're Hottentots, so he orders Mr. Binnacle to make them scram with colorful fireworks.  In the second part, as all the chimney sweepers get in the house of George Banks, Mrs. Brill walks into the living room looking at them and screams, "They're at it again!"  and she runs away trying to strike one of the chimney sweepers with a frying pan.  As Jane, Michael, Mary Poppins and Bert get in the same place, Ellen runs around the dining room with an "OW!"  and the chimney sweepers flip her.  The other phrases in the rest of the musical number are "Votes for women," "It's the master," and "What's all this?"
