Cover art for Surgical Focus lyrics by Guided by Voices

This song is about the healing process of a relationship that is translated into a metaphor involving surgery, cleansing, and waiting-lines.

The guy is healed and soars high with 'surgical focus'. More specifically it is probably about a guy that has loved a girl for a long time but has trouble reaching out to commit himself to such a relationship, and so is helped, happily, by the girl. A distinctly under-rated song.
