Yikes, need DSB audio help!

Okay, I'm in a spot and need some help... there's kind of a long story behind this, but what I'm looking for is a copy of Don't Stop Believin' from the '81 Houston concert with Perry's vocals kind of down in the mix - kind of like karaoke...
I work for an email marketing software company named iContact. We recently were nearing a big revenue milestone and the CEO asked the team what kind of crazy/embarrassing thing we'd do if we hit the target. Someone came up with the idea of reworking 'we are the world', changing the lyrics to be related to email and dressing like the original vocalists. Kinda dumb, but fun. A couple of us said that'd be a good idea and, following from others' lead, I said I'd be Steve Perry, complete w/ tuxedo tails. Well, turns out we hit the target and the CEO sent around an announcement of all the silly stuff we'd do to celebrate. One of the unexpected surprises included my singing DSB at the company lunch in front of 150 employees
So, I'm thinking I'll need the music and it'd be great to have the vocals lowered, but still audible, in hopes I can keep in tune. To top it off, everything nutty like this ends up getting posted on YouTube http://www.youtube.com/user/iContactTV
Can anyone help me with this? Or offer a tip of how I can lower the volume on Perry's vocals on that edition? Now I gotta find a wig an tuxedo tails...
Thanks,
DSB,
Ken
