White Hart Lane bounced all on sides as the fans were treated to one of the performances of the season in the Premier League.
Newcastle arrived in N17 in fine form, sitting fifth, with four wins in their last five league matches.
But the visitors were blown away in that opening 45 minutes.
Harry Redknapp made just one change to Monday's draw at Anfield with new signing Louis Saha in for his full debut alongside Emmanuel Adebayor in a 4-4-2 system. Jake Livermore was back on the bench, alongside the returning Aaron Lennon and Jermain Defoe.
Saha and Adebayor clicked immediately as Adebayor ran riot in the opening exchanges.
The Togo star put in one of the best individual displays of the season with four assists and a goal in the second half.
The first goal came with just over four minutes on the clock. Adebayor darted in from the right, played a one-two with Gareth Bale and looked like he was being shepherded away from goal by David Santon, but he managed to turn a cross back across goal and Benoit Assou-Ekotto gleefully rammed home from 10 yards.
It took just 90 seconds for the second goal - and a dream debut for Saha. Adebayor broke down the right, crossed and the French striker pounced from close range, a high, cushioned volley past Tim Krul.
Kranjcar blasted over but it was soon 3-0 as Assou-Ekotto threaded a pass through to Luka Modric, he found Adebayor who laid off for Saha to make it a quickfire double, drilling home from 14 yards.
Kranjcar was always involved and got his name on the scoresheet in the 33rd minute.
Modric led a break, Saha found Adebayor central and although Krul made a fine save, Kranjcar was there to drill home the rebound.
Four goals, 34 minutes - we didn't want the first half to end!
We were soon on the attack in the second half as Bale showed great vision to flick the ball to Adebayor, who couldn't get a shot off.
Adebayor then miss-hit a volley wide after a fine passing move and you were starting to think it wouldn't be his day, when...the fifth goal arrived on 65 minutes.
Bale went wide to Assou-Ekotto, he clipped in a cross that Saha won well, heading down to allow the Togo star to hook home a volley from close range. A richly-deserved goal.
That signalled the call for Jermain Defoe and Aaron Lennon to return from injury off the bench for Saha and Bale.
The next action was in the Spurs box and Friedel defended his clean sheet, showing great reactions to palm out Ba's close-range header. Dan Gosling followed up - and fired over the open goal.
Adebayor, twice, and Modric all went close before the final whistle - another match to remember.
