Who sings song on soundtrack?

I saw On our own several years ago and I really want to find the song in the film and the words I remember are hold on, hold on we're on our way. Can anyone check their video and respond with the correct song title and artist?
It is on in the scene shot in the air showing the kids vehicle driving down the road. I can't find the film or song anywhere.If anyone knows more words it would really help.
