Knock, Knock Who's There?

"Knock, Knock Who's There?" is a song written and composed by John Carter and Geoff Stephens, released on Apple Records. It was originally sung and recorded by the Welsh singer Mary Hopkin and was the 's entry at the Eurovision Song Contest 1970, where it came second. The single version was produced by Mickie Most and reached No. 2 on the UK charts.

Overview
On 7 March 1970, Mary Hopkin sang six songs at the UK National Final, A Song for Europe, which was aired on the television series It's Cliff Richard!. Hopkin was chosen by the BBC to be the United Kingdom's representative for that year, and the winner of a postal vote would determine which of the six songs would progress with her to the finals in Amsterdam. "Knock, Knock Who's There?", the sixth and final song performed that evening, won the postal vote with over 120,000 supporters.

At Amsterdam, the song was performed seventh on the night, after 's Guy Bonnet with "Marie-Blanche", and before 's David Alexandre Winter with "Je suis tombé du ciel". At the end of judging that evening, "Knock, Knock Who's There?" took the second-place slot with 26 points after 's "All Kinds of Everything", performed by Dana. The UK received points from nine out of a possible eleven voting juries.

The singer expresses a long-held optimism at the prospect of love finally finding her. At the exact point that said optimism has faded, and she has resigned herself to not finding love and companionship, she hears a "knock, knock", which signifies love finally becoming attainable for her. Excited, she beckons love to "come inside" and into her life.

The single was released in March 1970, backed by "I'm Going to Fall in Love Again" (the runner-up in the Song for Europe final) on the B-side. On 28 March 1970, "Knock, Knock Who's There?" entered the UK Singles Chart at No. 7, the highest new entry of the week. It peaked at No. 2 and remained on the chart for 14 weeks. It wasn't released in the United States as a single until November 1972, where it floundered for four weeks on the Billboard Hot 100, only reaching a peak of No.92. In the Netherlands it peaked at No. 3 on the Dutch Top 40 as well as on the Single Top 100.

Rather different from her usual material, Hopkin rarely performed the song after the Eurovision due to her distaste for it. She later commented: "I was so embarrassed about it. Standing on stage singing a song you hate is awful." She also referred to it as humiliating. At the time, she conceded victory gracefully saying that "the best song won" and wished Dana well.

In 1970, a sound-alike cover appeared on the album Top of the Pops, Volume 10.
