Roisin hit the streets of London today as part the BBC Culture Show's busking challenge. She performed a set of songs in London's busy Covent Garden area and tried to solicit as many donations as possible.
She is up against Moby, Hot 8 and former Pixies frontman Frank Black, who previously did some busking as part of the challenge.
Parts of Roisin's performance will be show on one of the upcoming editions of the Culture Show. You can visit the show's website here.
