The song she sang is the song Heaven from Bryan Adams back in the 80's. I got his song same melody in his compilation hits album. Seem she just re-sang it in her own way. It was a minor hit for Bryan Adams though. Google it
Heaven - Bryan Adams
Oh - thinkinÂ’ about all our younger years
There was only you and me
We were young and wild and free
Now nothinÂ’ can take you away from me
WeÂ’ve been down that road before
But thatÂ’s over now
You keep me cominÂ’ back for more
Baby youÂ’re all that I want
When youÂ’re lyinÂ’ here in my arms
IÂ’m findinÂ’ it hard to believe
WeÂ’re in heaven
And love is all that I need
And I found it there in your heart
It isnÂ’t too hard to see
WeÂ’re in heaven
Oh - once in your life you find someone
Who will turn your world around
Bring you up when youÂ’re feelinÂ’ down
Ya - nothinÂ’ could change what you mean to me
Oh thereÂ’s lots that I could say
But just hold me now
Cause our love will light the way
Chorus
IÂ’ve bin waitinÂ’ for so long
For somethinÂ’ to arrive
For love to come along
Now our dreams are cominÂ’ true
Through the good times and the bad
Ya - IÂ’ll be standinÂ’ there by you
