Siobhan Dillon

Dillon was 21 years old when she appeared on the BBC television show, How Do You Solve A Problem Like Maria?. She reached the final of the show and finished in third place behind Helena Blackman and winner Connie Fisher.[2] Despite being one of the favourites during the first round of auditions, Dillon initially did not make the final ten after an illness had affected her vocals during the final stages. However, after finalist Emilie Alford dropped out of the competition, Dillon, being the last person eliminated during the selection process returned to the show and was given the nickname, "Second Chance Maria".[4]

In week one of the live shows Dillon sang the Shania Twain hit, "Man! I Feel Like a Woman!". In week two she sang the Tina Arena song, "Chains". In the lead up to the third week's show, David Ian talked to the girls about fitness and stamina and sent them on a fitness test mission with Olympic track and field athlete Iwan Thomas, requiring the Marias to complete an assault course. Dillon completed the course in the fastest time of under two minutes. On the show she sang the Pointer Sisters hit, "Jump!". Zoe Tyler then asked her to sing the final lines from her audition piece, "I Could Have Danced All Night".

In week four she sang "Songbird" by Christine McVie, which resulted in her being named the unofficial "Maria of the night". Andrew Lloyd Webber chose her to perform "Truly Scrumptious" with the children from the musical Chitty Chitty Bang Bang. In the fifth week, when there were two live shows, she sang "All That Jazz" from the musical Chicago accompanied by six male dancers. Dillon successfully got through to the second live show of the evening but faced the second sing off with Aoife Mulholland. They sang "Don't Cry for Me, Argentina" from the musical Evita. Lloyd Webber saved Dillon because he believed she "had the strongest voice which could carry eight shows a week".

In the run-up to the final in week six, the three finalists and Lloyd Webber went to Salzburg in Austria and visited some of the locations made famous by The Sound of Music, including Leopoldskron Palace and Nonnberg Abbey, to give the finalists a chance to understand the real Maria von Trapp.[5] On the final night she performed two songs, "Anyone Who Had a Heart" and "My Favorite Things" from The Sound of Music. She was eliminated during the night's first public vote, which meant she came third overall.

Dillon made her West End theatre debut in 2007 playing Patty Simcox in the musical Grease. Her first appearance in the show was on 25 July 2007 at the Piccadilly Theatre in London.

Dillon won a record deal with Andrew Lloyd Webber’s company the Really Useful Group (RUG) after How Do You Solve a Problem Like Maria?.[10] She is said to be writing and recording her first album,[6] although on her Myspace page she is quoted saying, that after Andrew Lloyd Webber announced during one of the live How Do You Solve a Problem Like Maria? shows that "a major record label" were interested in working with her, she started writing songs for her album and worked with producers and writers but that "due to unfortunate circumstances the album was never released..."[12]
