Thousands of post-secondary students in Metro Vancouver benefit from a break on transit fares by using TransLink's U-Pass program, but thousands of others don't.

Now, those without are urging the BC Liberal government to level the playing field -- through song.

During the provincial election campaign last spring, incumbent premier Gordon Campbell pledged to make discounted universal bus passes available to all B.C. students by September 2010.

But a musical ad campaign posted to YouTube on Wednesday has a case to make about timeliness.

"Hey Mr. Premier, don't be slow -- because I've got classes where I've got to go," students sing.

"Hey Mr. Campbell man, we're not second class - you promised us a universal pass."

The ad was produced by student-run U-Pass advocate group One Pass Now, but it may be falling on deaf ears.

"It can't happen right now," TransLink spokesman Ken Hardie said. "TransLink is not in a position to afford it to happen right now. But yes, it can happen in the future and I think everyone hopes that it will."

Currently, universities and colleges including the University of British Columbia, Simon Fraser University and Langara College all offer students three-zone transit passes for as little as $24 per month.

Others, like Vancouver Community College, Emily Carr University and Douglas College still require students to pay full price for bus passes -- which amounts to $73 per month for a single zone.

"We've been asking for a U-Pass price that's not discriminatory against students for a long time," VCC student union member Nimmi Takkar said.

"We feel like it's not really negotiable at this point. We just need it."
