Italian and international singing guests become part of “story” of the evening’s broadcast, enlarging the musical panorama covered by that particular episode.
The guests stars perform without taking part in the competition, singing their greatest hits and engaging in duets with the younger singers.
The show is officially listed as part of "RAI Junior", but the audience includes not only young people but also their parents and grandparents who enjoy hearing these songs.
“TLUC” serves as a perfect link in the “musical chain” that connects the great sings of yesteryear with the magnificent voices of the performers of tomorrow.
Further enriching the program are anecdotes and little know facts on the songs covered in the competition, revealed by established singers, composers, actors and celebrities from the world of entertainment, with the additional contribution of commentary and filmed pieces from the period.
Guests included Liza Minnelli, Paul Anka, and Dionne Warwick, as well as numerous Italian singing stars.
The second season was broadcast live from the Teatro Ariston in Sanremo in nine episodes in April and May 2009, the performers ranging in age from 8 to 16 years old.
This was the season when producer Roberto Cenci put 14- to 15-year-old boys Gianluca Ginoble, Piero Barone, and Ignazio Boschetto together for the first time.
The fourth season began broadcasting live from the RAI Auditorium in Naples on 10 September 2010 and is projected to have 11 episodes, with the last one to be "La Festa".
The critics’ prize, on the other hand, is awarded by the members of the Quality Jury to the song they most admitted, based, first and foremost, on the way in which the young singer interpreted it.
