How about we give Hair Of The Dog a break today and reach back a bit further into Nazareth's past.  Chances are if you saw the band in concert back in the day, you'll remember This Flight Tonight.  It was a stage fave by the boys and also a pretty big hit in other countries, Canada for one, if I remember right.  A great track!  Check it out today around 5:20pm, either on the radio or on-line.
