Thomas provided some backing vocals for both "The Other Side of Life" and "Sur La Mer"; however, for reasons unclear, multiple production considerations led Visconti to leave Thomas' vocals off the latter of these two albums, thereby further reducing the texture of their overall vocal sound, which had previously been rich four-part harmonies (Hayward, Lodge, Thomas and Pinder), then went down to three (Thomas, Lodge and Hayward) upon Pinder's departure and reduced still further to just the more similar-sounding voices of Hayward and Lodge (Lodge also providing falsetto vocals and high harmonies), with Pinder and Thomas each having provided both lower and higher-pitched vocal harmonies in the group's earlier vocal sound. The band's vocal "sound" had become the blend of just Hayward and Lodge, which was still recognisable, if less textured than the original four-part, more complex "choral" sound. Moraz was displeased with Visconti's exclusion of Thomas from the final release of "Sur La Mer" and accused him of tailoring the album for radio, as revealed in a 1989 newspaper article where it revealed Moraz's anger with the state of the band and at Visconti in particular.
