La historia de McFly comienza en Londres, Reino Unido, a principios de la década de 2000. Tom Fletcher, el líder y principal compositor del grupo, inició su carrera en el mundo de la música como parte de la boyband Busted. Tras un fallido intento de audicionar nuevamente para Busted, Fletcher decidió explorar otros caminos. Fue entonces cuando conoció a Danny Jones en unas audiciones para un nuevo proyecto musical. Pronto quedó claro que ambos compartían intereses musicales y una visión similar, por lo que decidieron formar una banda.
Tom y Danny sumaron a Dougie Poynter y Harry Judd para completar la formación. Dougie, de origen neerlandés, fue el tercer miembro en unirse, trayendo consigo un estilo distintivo en el bajo y voces secundarias. Harry, por su parte, aportó la energía y precisión que el grupo necesitaba en la batería. De esta manera, en 2003, McFly emergió como una banda completa.
En 2004, el grupo lanzó su primer sencillo, "5 Colours in Her Hair", que rápidamente alcanzó el número uno en las listas del Reino Unido. Con un sonido fresco que combinaba pop punk y rock, McFly atrajo la atención de jóvenes fanáticos y críticos por igual. Ese mismo año, lanzaron su primer álbum "Room on the 3rd Floor", el cual también dominó las listas.
I remember playing games
And wishing we were older then
We were so much younger then
Those were the days
I remember holding your hands
And thinking it would never end
We were so in love back then
Those were the days
Those were the days of innocence
And we were so naïve
You would lie down in the grass
All tangled up in me
Always wasn't just a word
But something to believe
We had our entire lives to waste
Those were the days
Ooh-ooh-ooh-ooh-ooh
Those were the days
Ooh-ooh-ooh-ooh-ooh
Time was so much slower then
Seven turned to seventeen
Somewhere in the in between
Those were the days
Back before we realized
Hearts were small and fragile things
We said, "I do", with jelly rings
Those were the days
Those were the days of innocence
And we were so naïve
You would lie down in the grass
All tangled up in me
Always wasn't just a word
But something to believe
We had our entire lives to waste
Those were the days
Ooh-ooh-ooh-ooh-ooh
Those were the days
Ooh-ooh-ooh-ooh-ooh
I still have the note you wrote
Said, "I'll miss you darling, be back soon"
Four pictures from a photobooth
You were laughing, I was kissing you
And kissing you
God, I'm missing you
Nothing ever stays the same
Glad we didn't know it then
'Cause we were so much younger then
Those were the days of innocence
And we were so naïve
You would lie down in the grass
All tangled up in me
Always wasn't just a word
But something to believe
I still miss you in a thousand ways
Those were the days
Ooh-ooh-ooh-ooh-ooh
Those were the days
Ooh-ooh-ooh-ooh-ooh
Those were the days
Ooh-ooh-ooh-ooh-ooh
Those were the days
Ooh-ooh-ooh-ooh-ooh
