Hugo & Luigi

First coming to attention with singles released on Mercury Records in the mid-1950s, they went on to produce Perry Como, Sam Cooke and several other RCA Victor artists, including the hit records "Twistin' the Night Away", "Another Saturday Night", "The Lion Sleeps Tonight" by the Tokens, "Shout", a classic by The Isley Brothers, and "I Will Follow Him" by Little Peggy March.

They co-wrote Elvis Presley's hit "Can't Help Falling in Love", with George David Weiss.

Their track, "La Plume de Ma Tante" (written by Al Hoffman and Dick Manning), reached #29 in the UK Singles Chart in July 1959.

Songs composed by the duo were often credited to "Mark Markwell", and records they produced carried their distinct logo.

It was announced in the 30 January 1960 issue of The Cash Box that Mike Collier had taken on the role of personal assistance in the Artists and Repertoire Department.
