Composer of Here Comes the Bride?

It is actually the Bridal March from Richard Wagner's "Lohengrin". I haven't seen the opera, but assume the original lyrics (sung by the bridal chorus) are in German.

The Bridal March is from Wagner's Lohengrin.

Here comes the Bride or the Wedding March comes from the opera Lohengrin, by the German composer Richard Wagner. Or if you are thinking of the one (see link related below) Felix Meldelsohn

The Romanian language equivalent of ''here comes the bride'' is aici va veni mireasa.
