An extremely hot week was further intensified by a high voltage show from AC/DC at Hampden on Tuesday.
With a rumble of a train crashing on to the stage, the energetic performance thundered off the tracks with Runaway Train.
Over 2 hours of stompin' rock classics such as Back in The Black, Hells Bells, T.N.T, Dity Deeds, encored with Highway to Hell and For Those About To Rock quenched the Glasgow crowd.
Never pretending to be anything more than a good time rock n roll band Brian Johnson kept on spittin out the gravel while Angus Young, duck walked, stripped, (yes) and ran whilst machine gunning licks from his geetar.
All this and Bruce in 2 weeks too - what a summer this is.
