"Oh What a Circus" was a commercial success for Essex, who had been dropped by his previous record company due to his declining sales. The song reached number 3 on the UK Singles Chart, and the top-30 in Belgium and Netherlands. In subsequent productions of the musical, "Oh What a Circus" has been sung by numerous performers, including Mandy Patinkin, Ricky Martin and Scottish rock musician Marti Pellow. In the 1996 film adaptation of the show, the song was sung by Antonio Banderas and American singer Madonna, and received critical appreciation for its flamenco-infused composition.
