 We were up to daylight
 Swimming in the dark
 By the time to get home
 We'll sleep under the stars

 Little worry 'bout tomorrow
 We were young, we were free
 And everything was easy
 That summer you and me (hey)

 We used to live like kings while following the sun
 And dance all night but never stay for long
 The road was our only home, we had it all, oh
 We were wild at heart

 Wild at heart
 We were wild at heart
 Wild at heart
 We were wild at heart

 Wild at heart
 We were wild at heart
 Wild at heart
 We were wild at heart

 Little worry 'bout tomorrow
 We were young, we were free
 And everything was easy
 That summer you and me (hey)

 We used to live like kings while following the sun
 And dance all night but never stay for long
 The road was our only home, we had it all, oh
 We were wild at heart
 We were wild at heart
 Wild at heart
 Wild at heart
 We were wild at heart
 We were wild at heart

 Wild at heart
 We were wild at heart
 We were wild at heart
 We were wild at heart
