Haydn's operas are rarely staged, and when they are, unfavourable comparisons with Mozart are often drawn. That's not an unfair assessment, but Haydn's comedies have merits of their own - as amply demonstrated in English Touring Opera's Regency period revival of L'Infedelta Delusa, wittily translated by Gerard McNamara as Country Matters.

With just five characters and a small orchestra, the piece proves ideal for touring. The plot concerns Filippo, a peasant whose ambitions for his daughter Sandrina centre on marriage to the banker Nencio. Sandrina, however, has eyes only for Nanni, a neighbour, while Nencio is betrothed to lively Vespina. Inevitably, the two young couples are happily paired off by the curtain, though not without the usual opera buffa intrigues and disguises on the way.

Soprano Charlotte Ellett enters fully into the physical aspects of Vespina's role, especially the impersonations of the second act - a frail old woman, a lawyer and an admiral. Due to her vocal indisposition on this occasion, however, the singing was handled, equally adeptly, from the wings by Jeni Bern.

Andrew Staples makes a splendidly amiable figure of Nencio, while Huw Rhys-Evans plays Filippo with consternation eventually giving way to good grace. Jonathan Gunthorpe's Nanni and Lorina Gore's Sandrina are alert and vocally precise.

Adam Wiltshire's designs sketch in an aptly idyllic rural background, director Liam Steel keeps the comedy moving on the lightest of feet, and conductor Justin Doyle maintains musical dynamism. Even if the result does not quite reach Mozartean heights, Haydn's opera makes a more than acceptable change.
