Roper has toured the character internationally, performing in Spain,[2] Italy,[3][4] the Czech Republic,[5] Germany,[6] Hungary,[7] Slovakia,[8] South Africa,[9] Australia,[10] Argentina, and Iceland.

[11][12] Physically, the character of Wilfredo is a grotesque caricature of Falstaffian appearance: trousers pulled up to the top of a corpulent stomach, a tight flamenco shirt, a wild black mop wig and a set of prominent prosthetic teeth.

[16] The character began his life onstage performing cover versions of songs by Leonard Cohen, Phil Spector, Amy Winehouse and the Rolling Stones.

The character made his London debut at Camden Town's Lockstock Festival in November 2008, performing a cover of the Amy Winehouse song Rehab.

[19] Encouraged by the positive reception of these appearances, Roper began to perform Wilfredo sporadically until the summer of 2009 while writing and exploring the concept of the character more fully.

Featuring the character Mana Maria on guitar, Wilfredo performed covers (Leonard Cohen's Hallelujah), parody (Those Were The Days) and original songs from a fictionalized back catalogue of albums.

Various affairs with prominent women including Victoria Beckham, American First Lady Michelle Obama and the Princess of Wales are claimed for the first time in The Child Is Not Mine, which becomes a flagship signature song.

[28][29] I found myself sucked delightfully into his weird and wonderful world, as he dexterously fondled the funny bones of the modest crowd: about a dozen people clustered around a handful of lantern-lit tables.

Whether you were laughing at his megalomaniacal afflictions, grimacing at his trademark mouthful of mammoth ivories (he was "born with the full set", if you ever wondered) or at his penchant for phlegmatic hacking – salivating and interspersing his satirical musings with mucus filled eruptions – it was difficult not to be seduced by this Spaniard's musical ruminations.In March 2011 Wilfredo enjoyed a limited season at the Leicester Square Theatre[31] where he began to preview new material for the forthcoming Edinburgh Festival Fringe.

In addition, on 16 June Roper presented the character to an audience at the Poetry Society in Covent Garden,[33] reciting a spoken-word version of Leonard Cohen's 'Hey, That's No Way To Say Goodbye'.

"[37] The British comedy industry website Chortle noted the character as "sometimes cantankerous, often lecherous and almost certainly consumptive... coughing and burping his way through the set, at one point hacking up phlegm like a horse chewing a toffee"[14] while the critic at ThreeWeeks lauded Wilfredo as both "disgusting and arousing".

On 6 July Wilfredo performed in Arthur Smith's Benefit for the Royal Yacht at the E4 Udderbelly at the Southbank Centre, an alternative Queen's Diamond Jubilee Concert.

For all the parody (which could so easily descend into dated, 2D 'funny foreigner' stuff) the joke is perhaps on us"[55] while Kate Copstick of the Scotsman newspaper hailed the character as "a master of seduction" and the music "timeless".

[56] Such criticism was later lost on BBC Radio 2, who banned Peace All Over The World (At Christmas Time) – a festive single release by the character in a duet with the comedian Pippa Evans under the guise of Latino star Carmella – on the basis of "daytime listeners being offended".

[57] Wilfredo embarked on a Spring tour of the Asia-Pacific region in 2015, having opened at the Adelaide Fringe on 1 March and giving performances in Manila, Philippines, Singapore and at the Melbourne International Comedy Festival.

[58] Presently Wilfredo makes regular weekend appearances at the Slipper Room, a vaudeville and variety theatre in the Lower East Side of Manhattan, New York City.
