In this soaring rock duet, Italian tenor Andrea Bocelli and English soprano Sarah Brightman transform a simple farewell into an electrifying promise: when darkness steals your words, the presence of a loved one becomes the missing sunlight, urging you to fling open the windows and reveal the light inside. Their rallying cry of "Time to say goodbye" is not a sad ending but an invitation to adventure, as they vow to sail imaginary seas, explore countries only dreamt of, and relive them together. The chorus reminds us that true love turns parting into bold discovery, replacing fear with hope and inviting us to step beyond the horizon side by side.
