A Single Man Tear Sam sings A single man tear slips down his face He shows emotion without a trace He hides behind a mask so strong Worried that he could be wrong I wish that he could see the way I see him The perfect brother, a man without sin Cause underneath the manly sheen It is my brother, a boy named Dean A single man tear, a single man tear, a single man tear, that’s all we fear Dean sings A single man tear, that’s all I’ll spare I bury feelings, don’t show I care Even though I am haunted, must be the man daddy wanted Wish I could be as strong as Sam Blaze my own trail, be my own man But underneath this broken mask It is my father, with all his wrath A single man tear, a single man tear, a single man tear, that’s all we fear – Lyrics by Robbie Thompson and Christopher Lennertz, sung by Katie Sarife, Alyssa Lynch; music by Christopher Lennertz and Cameron Stone
