Spring [bad word] around and there's no hero's to be found
There's something major going down on Tracy island (Island) 

Weapons underground keeping the planet safe and sound 
If someone [bad word] round he should be frightened (Frightened) 
Cause now the boys are back in town
No strings to hold them down, down

Don't be mad please, stop the hating
Just be glad that they'll be waiting
Friends we have are ever changing no
Now the lid's about to blow
When the thunderbirds are go

Kids are learning fast they know their team birds kick some [bad word] Be sure that there's [bad word] last cause your on their side (Their side) 

You always look so cool when [bad word] out of the pool
You know that you'd just be a fool to be a bad guy (bad guy) 

Cause now the boys are back in town
No strings to hold them down, down

Don't be mad please, stop the hating
Just be glad that they'll be waiting
Friends we have are ever changing no
Now the lid's about to blow
When the thunderbirds are go

Thunderbirds are go, go, go, go

Don't be mad please, stop the hating
Just be glad that they'll be waiting
Friends we have are ever changing no
Now the lid's about to blow
When the thunderbirds are go

Thunderbirds are, Thunderbirds are go

Thunderbirds are, Thunderbirds are go

Thunderbirds are, Thunderbirds are
Thunderbirds are go
