Friends Till The End



On the first day that I met you
Feeling out of place, so many new faces
The first friend that I looked to
When I reached out, you'd always be there for me



Friends till the end, never break, never bend
Friends understand, make you smile, hold your hand



Now we're standing together, we're never alone
And we shine a light wherever we may go



If you need me in a heartbeat, just say so
You can count on me, count on me
I will come in a heartbeat 'cause you know
You will always be, always be number one



The first time I sung a song
Finding my feet, the right melodies to key
The first time you sung along
It was real harmony, like you were a part of me



Friends till the end, never break, never bend
Friends understand, make you smile, hold your hand



Now we're standing together, we're never alone
And dreams are alive, gonna keep believing
The friendship we share like the music we love
It keeps us together wherever we may go



If you need me in a heartbeat, just say so
You can count on me, count on me
I will come in a heartbeat 'cause you know
You will always be, always be number one
