Only two singles were produced from Careful What You Wish For. The first was the hit UK Top 10 single, "Carnival Girl" which reached #9 on the UK Singles Charts and was also a hit in other European countries.
A second single, "I'll See It Through" was released in December 2003. However, the single was less successful than the release of "Carnival Girl", only debuting at #40 on the UK Singles Charts. After this their record label, Mercury Records, decided not to release a third single from the album, and this led Texas to re-enter the studio to start work on their next album, Red Book (2005).
