[3] At the conclusion of the project the core group of performers including Antonella Casella, Chris Sleight, Lisa Small, Ceri McCoy, Chantal Eastwell, Robbie McNamara, Richard Teatro, Sally Herbert and later Derek Ives, expressed interest in continuing as an independent faction to exclusively perform circus.

[4] Originally an ancillary activity by Street Arts, the troupe evolved to performing their own unique brand of circus fused with music and theatre.

Lifschitz, the youngest graduate from NIDA's prestigious directing course,[8] made the controversial move to rename the company 'Circa' in 2004, rendering Rock n' Roll Circus' history and legacy into obscurity.

Circa also relates to the same word as circus‚ 'in around, about' which "captures [the company's] questing, questioning attitude" and noting its linguistic similarity in many languages.

[16] To date, the company has performed with both pre-recorded and live music, but unlike its gritty, raw, rock n' roll origin, Circa tends to feature the score of Mozart, Monteverdi and Shostakovitch.

Following the 2012 collaboration of Love-Song-Circus at Adelaide Cabaret Festival, Katie Noonan released the album Fierce Hearts which contained the musical score and songs which accompanied the show.
