We had "Wonderful World" as our first dance at our wedding. During the ceremony, my brass ensemble played an arrangement of "Night and Day". I played too, then went and signed the register while they played on. It sounded great (and the words would have been appropriate if they'd been sung)... not so sure though that it would sound quite as good as a solo? Maybe you could start with that and move into "Wonderful World". If you take your time over the first three notes, it sounds as if you're just warming/tuning up
