[3] Treble writer A.T. Bossenger wrote that, with Casanova, Divine Comedy frontman Neil Hannon "started going for a more straightforward pop tone as the base for his songwriting", resulting in the album having a more Britpop flow to it.

[1] Jeremy Lee of ABC News considered that this record brought Neil Hannon "closer to the orchestral pop sound he'd been dreaming of.

Two of Casanova's songs were originally composed by Hannon as potential theme tunes for the 1995 sitcom Father Ted: Hannon's first attempt was rejected, and he reworked it to become "A Woman of the World"; his second attempt was accepted and used as the theme for the series, but was later reworked as "Songs of Love", eschewing the original version's guitar for harpsichord.

[6] The album's closing track, "The Dogs and the Horses", recorded at Abbey Road Studios, features a large orchestral ensemble which includes future members of the live band, namely Joby Talbot, Stuart 'Pinkie' Bates, Grant Gordon, and Bryan Mills.

Talbot was beginning to play an increasingly important role in the band; he arranged and orchestrated "The Dogs and the Horses," and he co-arranged "Theme from Casanova" with Hannon.
