We caught up with first violinist Bróna Cahill to see how the RTÉ Concert Orchestra is preparing for their performance on Dancing with the Stars this Sunday, February 23rd. 

After the success of last year's Orchestra Night, the RTÉ Concert Orchestra are set to grace our screens again on DWTS. 

They will be playing live for the seven remaining contestants on the show and we can expect an exciting mixture of swing, tango, pop and alternative music on the playlist. 

As you might expect, the RTÉ Concert Orchestra is very busy. They’ve most recently been performing in the sold-out A Woman’s Heart Orchestrated concerts alongside Eleonor McAvoy, Maura O'Connell and Wallis Bird. 

Bróna informed us that they started rehearsals for DWTS last week and will "tweak" and "perfect" all of the pieces for the show in a rehearsal this weekend before showtime on Sunday night. 

Unfortunately, Bróna was sick during the Concert Orchestra’s performance on the show last year, so she’s "looking forward to doing it this year".

She’s making up for last year’s absence, however - for Sunday’s show, Bróna will not only be leading the orchestra but also playing a solo for Mary Kennedy’s performance. 

When asked how she feels about leading the orchestra, she noted how much of an honour it is: "The RTÉ Concert Orchestra is made up of fine, highly-skilled, really really well-trained musicians, so to be able to lead them is a serious privilege." 

The solo Bróna will be playing for Mary Kennedy’s performance also happens to be one of her favourite pieces - and no, we can't reveal it in advance. 

The RTÉ Concert Orchestra’s performance on DWTS last year was very well received by the public, with the CO trending on social media. 

Many people noted how the addition of the Concert Orchestra added extra layers of drama and energy to the show, and the contestant's performances.

According to Bróna, the orchestra was delighted with all of the positive feedback they received from last year's DWTS performance, noting that the positive feedback from the public lifts the spirits of the orchestra members and "makes it special".
