Narrative:

After push back onto active taxiway a; and a minute or so after disconnect; we received taxi clearance and I was pushing engine power up for taxi (taxi light on) when a station tug pulled from the right in front of aircraft blocking our taxi. My alert first officer called my attention to the tug as it was approaching and I pulled engine power back to idle; engaged the parking brake; and turned off the taxi light. My first officer canceled taxi clearance. The supervisor on the tug then connected to the aircraft ground comm cord to ask if a particular passenger was on board. If our attention had been distracted with aircraft checklist duties; I could very easily have collided with the tug. The passenger information could have easily been passed by ACARS or radio after departure; rather than interfering with an aircraft about to taxi.
