[5] Other performers involved in the series included Laurence Dale, Della Jones, Harry Nicoll, Jill Washington, Jean Bailey, Hugh Hetherington, Neil Jenkins, Eirian James, David Fieldsend, Linda Ormiston, and Ramon Remedios.

[4] Sean Day-Lewis, writing in the Daily Telegraph, expressed the view that the programme was a "slickly assembled and more or less uncorrupted sequence of melodies from operetta and musical comedy", and that "it was an excellently finished video which would have won a high rating indeed on one of the senior channels".

[8] The Listener magazine noted that "the programme conveys a sense of fun, and at least it resuscitates some sparkling operetta tunes"[9] Former Channel 4 Chief Executive Jeremy Isaacs wrote about Top C's and Tiaras in his 1989 memoir, Storm Over 4.

He quoted examples of the influx of appreciative telephone calls from viewers for the first edition, that were logged in the Duty Officer's report for April 10, 1983, and said that Top C's and Tiaras, "though made on a shoestring, went down a treat with the fans".

A number of CDs based on the program, Treasures of Operetta, featuring Marilyn Hill Smith and Peter Morrison, were released by Chandos Records between 1985 and 1989.
