A Logic Puzzle

A foursome of golfers is standing at a tee, in a line from left to right.
Each golfer wears different colored pants; one is wearing red pants.

• Joe is second in line.
• Bob is wearing plaid pants.
• The golfer to Fred's immediate right is wearing blue pants.
• Tom isn't in position one or four, and he isn't wearing the hideous orange pants.

In what order will the four golfers tee off, and what color are each golfer's pants?
