In my recording I used the sheet music as my primary guide rather than attempting to imitate the Boswells' innovative arrangement. Like the Boswells, I did omit the introductory verse, which includes these explanatory lyrics:
"In old Madrid I met a sweetie not very long ago,
And all we did was sign a treaty to love each other wherever we go.
It wasn't just a scrap of paper, and when I'm all alone
I call up Spain and sing again this sweet refrain over the telephone..."
For the second bridge, I did take the liberty of adding my own lyrics, inspired by a common practice of the Boswells. It can get boring returning to the bridge and keeping the same lyrics, or just whistling the melody, so for variety I sing:
"Remember how you love me now,
no matter who you find;
If you're wise, you'll close your eyes;
love is blind, but it can slip your mind..."
