Paul McCartney and Mary Hopkin both made appearances on a TV show made in the UK for US audiences on this day.
The programme was David Frost Presents...Frankie Howerd, which was intended to introduce comedian and actor Howerd to American audiences. It was filmed at Stonebridge House in Wembley, London, where production company InterTel (VTR Services) was based.
The original date for filming was to have been 2 June, but had been pushed back due to scheduling conflicts. David Frost Presents... was essentially a vehicle for showcasing British talent, and McCartney used the opportunity to bring Hopkin to a wider audience.
McCartney was interviewed by Howerd, with questions scripted by Frost. They discussed The Beatles' intentions for Apple, and how they hoped it would support new talent. McCartney then introduced Hopkin, who performed House Of The Rising Sun.
David Frost Presents...Frankie Howerd was first shown the following year, on 23 February 1969 from 6-7pm EST.
InterTel had previously made promotional clips for I Feel Fine, Ticket To Ride, Help!, Day Tripper, We Can Work It Out, Paperback Writer and Rain. Stonebridge House was also where The Rolling Stones' Rock And Roll Circus was filmed, and which featured appearances from John Lennon and Yoko Ono.
