In my fifteen minutes of googling, I haven't managed to figure out exactly which bill or resolution it was that Elmo was speaking on, but it was probably
H.CON.RES.343 -- Expressing the sense of the Congress supporting music education and Music in Our Schools Month.
Which was a resolution introduced on March 7th, 2002 (Elmo spoke on April 23, 2002) and co-sponsored by Rep Cunningham.
The resolution is essentially an empty document which states that it is the "sense" of Congress that schools should have music education, pay qualified music teachers, commend them for advancing music education and encourage research into whether music "contributes to the cognitive development of Children".
Also, it states that "Music in our Schools Month" (March 2002) is a good idea.
It provides no money or resources of any kind, nor any regulations, expectations or statutes.
It was referred to the House Committee on Education and the Workforce on March 7th, and then on May 5th sent to the Subcommittee on Education Reform where it was never looked at. It languishes there to this day, some 102 months since "Music in Our Schools Month."
But having Colbert come and speak about the conditions facing migrant farm workers is a waste of time and money.
