Down A Long Lonely Road lyrics

Down a long lonely road I've been cryin', lookin' 4 someone 2 care
Down a long lonely road I've been cryin', lookin' 4 someone 2 care
Down a long lonely road I've been cryin', lookin' 4 someone 2 care
Down a long lonely road I've been cryin', lookin' 4 someone 2 care
[repeat]
