Fast forward 10 years and the lads are still going strong, Tom has a cute wedding video with over 10 million hits on YouTube, Dougie won I'm A Celebrity...Get Me Out Of Here, Harry won Strictly Come Dancing and thouugh Danny has kept more to himself, he's still awesome.
But anyway, the guys went on a tour and we got to see them on their final gig at Wembley Arena.
The nostalgia started straight away with the first opening act being James Bourne from Busted!
We really hope the lads really are considering appearing on The Big Reunion because they were such a good band.
Next up was The Vamps who were the cutest things we've ever seen. Basically One Direction meets Mcfly, the lads had no trouble covering 1D's little things.
But having recently been signed to EMI records, we think things look promising for those boys.
Then it was on to the main show and Mcfly did not disappoint!
Whizzing through all of their biggest tracks and a few new ones, the guys looked completely at home on the stage.
Five Colours In Her Hair, Obviously, One For The Radio, Shine A Light and all the other faves got a great reception.
And naturally All About You had everyone swaying along.
As Tom said, it was amazing to see just how many fans are still buying tickets and are so full of energy for the band.
The lads might have been kicked up in their suit and tie but they bounced around the stage with the same energy as they always have.
With the likes of JLS calling it quits, we think Mcfly need to get a pat on the back for doing so well.
If you're a fan then you need to go to their special gig at London's very-swanky Royal Albert Hall where surprise guests have been promised.
After the show we saw last night, we're sure it's going to be a great night.
Barclaycard Unwind gives you easy access to even more of the events you want to see, including music, comedy, exhibitions and theatre events.
Will you be buying tix to see the lads?
