Blind Faith

I have seen this TV movie twice - and even though it seemed a little dragged out - I thought that the three sons were wonderful - not just as the sons and their reactions to their father - but all of CD) whatever, and he starts mouthing the words, and then recalls being in a car with his (now dead) mother, and she joins in the song and they spend a special time together. I loved the song, but I do not know who sings it or who wrote it, and would like get it. It's "hook" is 'Its a long way home". Can anyone help me on this? It is by a group I think and is on an album, but I couldn't catch the name from the TV movie.

Thanks.
