Input: Consider Input: Passage: It is not clear why, in 1873, Alkan decided to emerge from his self-imposed obscurity to give a series of six Petits Concerts at the Érard piano showrooms. It may have been associated with the developing career of Delaborde, who, returning to Paris in 1867, soon became a concert fixture, including in his recitals many works by his father, and who was at the end of 1872 given the appointment that had escaped Alkan himself, Professor at the Conservatoire. The success of the Petits Concerts led to them becoming an annual event (with occasional interruptions caused by Alkan's health) until 1880 or possibly beyond. The Petits Concerts featured music not only by Alkan but of his favourite composers from Bach onwards, played on both the piano and the pédalier, and occasionally with the participation of another instrumentalist or singer. He was assisted in these concerts by his siblings, and by other musicians including Delaborde, Camille Saint-Saëns, and Auguste Franchomme.Those encountering Alkan at this phase included the young Vincent d'Indy, who recalled Alkan's "skinny, hooked fingers" playing Bach on an Érard pedal piano: "I listened, riveted to the spot by the expressive, crystal-clear playing." Alkan later played Beethoven's Op. 110 sonata, of which d'Indy said: "What happened to the great Beethovenian poem ... I couldn't begin to describe – above all in the Arioso and the Fugue, where the melody, penetrating the mystery of Death itself, climbs up to a blaze of light, affected me with an excess of enthusiasm such as I have never experienced since. This was not Liszt—perhaps less perfect, technically—but it had greater intimacy and was more humanly moving ..."The biographer of Chopin, Frederick Niecks, sought Alkan for his recollections in 1880 but was sternly denied access by Alkan's concierge – "To my ... enquiry when he could be found at home, the reply was a ... decisive 'Never'." However, a few days later he found Alkan at Érard's, and Niecks writes of their meeting that "his reception of me was not merely polite but most friendly.". 
Question: Whose reception of Niecks was reportedly not merely polite but most friendly?

Output: Alkan.

Input: Consider Input: Passage: Johnston was born on 23 September 1994 in Dumfries, Scotland, the son of Andrew Johnston and Morag Brannock. He was given the extensive name Andrew Aaron Lewis Patrick Brannock John Grieve Michael Robert Oscar Schmidt Johnston. Johnston's parents separated when he was eight months old, and from that time he lived with his mother and three older siblings in Carlisle, Cumbria, in the north of England, where he attended Trinity School. Johnston tried out for Carlisle Cathedral Choir at the age of six at the recommendation of Kim Harris, a teacher at his primary school. He was auditioned by the choirmaster Jeremy Suter and accepted into the choir at the age of seven. Johnston's mother, who had no previous association with the cathedral, described her feelings of being overwhelmed by emotion at having her boy singing in such a "stunning building among those extraordinary voices". His mother also described Johnston's busy regimen of practice four times a week and all day Sundays, saying that it took up all of their spare time. However, she said that the cathedral staff became like a family to her son, and that "it was such a lovely, safe, close feeling for him". Johnston, who attended Trinity School, was subject to abuse and threats from bullies which drove him to contemplate quitting the choir, but he was helped through the ordeal by his choirmaster and the dean and canons of the cathedral. By the time of his participation in Britain's Got Talent, Johnston was head chorister.In September 2008, after his appearance on Britain's Got Talent but before the release of his first album, Johnston embarked on a tour of Norway with the choir, performing at Stavanger Cathedral and Utstein Abbey, among other places. The tour was conceived because the Diocese of Stavanger is connected with the Diocese of Carlisle through the Partnership for World Mission. This was Johnston's last tour with the choir. Johnston features as head chorister on one of the choir's albums, The Choral Music of F.W Wadely, released in November 2008. 
Question: What is the last name of the person whose mother described feelings of being overwhelmed by emotion at having her boy singing in such a "stunning building among those extraordinary voices"?


Output: Johnston.
