Envelope lyrics by Shaun Mangan It hid the letter that I sent her from the secret spies Signed, sealed, sent away. Hidden from the eyes of the spies it held all I had to say. I thought a letter would be better, though I can't recall it at all. I stamped it double weight. I can't recall it at all, but it concealed my fate. Envelope. My envelope. I set it sail through the mail to a valentine of mine, so much like all the rest. Straight to a valentine of mine, but she'll love mine the best.
