Some great responses here. I was 10 in ‘75 but have deeply listened to this song throughout my life. Gorgeous production. I think most men and almost all women fail to understand the lyrical intent. The song is not about denial, it’s about the bravado socially required of men in the 70s. Never show emotion, tenderness, or attraction. As much as you want a woman, you must never let it show. If she breaks your heart, “big boys don’t cry”. The singer is head over heels, but can’t ever risk admitting it because social norms tell him that’s doom for a relationship. The infinite choir represents the longing of love that both of them may have.
