"A mix of black-tie class, charm, wit and impeccable musicality" sounds like a recipe for a good night out. And that is what's promised by the Oxford Gargoyles, a jazz a cappella ensemble from the world's second-oldest (surviving) university.

Hailing from Britain's Oxford University, the Gargoyles have been described as "charm personified" and certainly their outfits ooze jazz pizzaz (think sleek tuxedos and little black cocktail dresses). Coupled with broad smiles and contagious enthusiasm for music they're creating with nothing more than their vocal chords, it's enough to charm the pants right off you.

The Gargoyles - few of whom, judging by their photos, are as grotesque as their architectural namesakes - have performed in New York's Lincoln Centre and at the Edinburgh Festival Fringe. Now, they are making their first trip to Asia, with a tour to Hong Kong and Macau later this month. The group will give performances at City Hall, Grappa's Cellar, Backstage Live and the Fringe Club and rumours suggest there will be surprise serenades at some of Hong Kong's iconic spots and events, including The Peak, Central MTR station and the Rugby Sevens.

If you're still not sure they are for you, watch their rendition of Beyonce's Crazy in Love on YouTube. The pop diva's vigorous vocals and sexy shimmying may not seem an obvious choice for a group of 12 Oxford geeks, but the Gargoyles manage to pull the song off in style. Who needs Beyonce's curves when, according to the BBC's Strictly Come Dancing judge Craig Revel Horwood, you've got "scintillating harmonies, swinging rhythms and superb showmanship"?

The performances that we do know about will take place from March 21 to 29, with a final show in Macau on April 1, of which all proceeds will benefit Macanese elderly association Associacao de Mutuo Auxilio do Bairro.
