[Verse 1]
Rainy days singing songs out on Grafton street
Got so cold I didn't know I couldn't feel my feet
That's how I know it's Christmas
Christmas night, having pints out in the wishing well
Haven't seen you for a while, yeah, but you're looking well
That's how I know it's Christmas

[Pre-Chorus]
And I'm home, and I'm home

[Chorus]
That's how I know
That's how I know
That's how I know
It's Christmas at home

[Verse 2]
I've got my family and my friends, my lady's on her way
I go to meet her off the train, yeah, but it's running late
That's how know it's Christmas
She said, "I missed you", and I said, "I missed you too"
I'm just so happy to have all my favourite people standing in the room
That's how I know it's Christmas

[Pre-Chorus]
And we're home, and we're home
[Chorus]
That's how I know
That's how I know
That's how I know
It's Christmas at home, yeah
That's how I know
That's how I know
That's how I know
It's Christmas at home, yeah

[Bridge]
Give it to the choir
Ding dong, ding dong
Ding dong, ding dong
Ding dong, ding dong
Ding dong, ding dong
Ding dong, ding dong
Ding dong, ding dong
Ding dong, ding dong
Ding dong, ding dong
I can't believe, its been a year since I was standing here
This is all I ever want, I'm so happy
That's how I know it's Christmas

[Chorus]
That's how I know
That's how I know
That's how I know
It's Christmas at home, yeah
That's how I know
That's how I know
That's how I know
It's Christmas at home
