Ferri Llopis was soon after called up for military duty. Suffering from depression, he later contemplated quitting singing. While Ferri Llopis was away on military duty, his empresario López befriended Miguel Siurán, a radio personality, who was impressed by Los Superson's sound and wanted to help them get a recording contract. López declined as he felt Ferri Llopis should be included. When Ferri Llopis returned from his military service, López talked to him about the contract, but Siurán was initially doubtful, questioning the young man's singing ability, asking if he could sing like Tom Jones, Engelbert Humperdinck or John Rowles.
