During his British visit on July 16, 1967, Feliciano gave a live performance on the pirate radio stations Radio 227 and Radio 355, on board the MV "Laissez Faire" off the British coast less than a month before the stations were due to be closed by the UK's Marine Broadcasting Offences Act. He also guested on a popular British television show with Dusty Springfield and recorded a rare single for RCA in England called "My Foolish Heart / Only Once" which was played on London radio . Earlier, on June 4, 1967, in London's Speakeasy Club, Jimi Hendrix came to the stage and complimented Feliciano on his extraordinary guitar work.
