Pump it up is so repetitive that it's not going to be much of a reading exercise. Use it as a ear training exercise, and get something else for the reading. I'd go with some of the old James Jameson bass lines - he always had a lot of that melodic content that Bruce Thomas had, but with a more laid back feel (or, more acuratly, Bruce Thomas tried to get some of the melodic complexity that Jameson had, but with more attitude). Or some of the other Elvis Costello things - there are plenty of places where Bruce Thomas did some amazing bass part. You'll probably have an easier time finding the Jameson stuff, though.
I've always loved Bruce Thomas' parts though. And to think, they almost didn't let him audition because when they asked him who his influences were, he said Steely Dan (and the Ramones, but it was the Dan that freaked out Elvis' managers!)
