Gentlemen callers not allowed - Gilla

Although 'Gentlemen callers not allowed' was presented as a single by Gilla & Bobby at some point, but originally it was simply a single by Gilla on her own, as this sleeve demonstrates. So it isn't strange that I thought I didn't already have the track. Unfortunately the content of the single is identical, including the vocals of Bobby Farrell (or should I say, Frank Farian?). 

After the birth of her daughter, Gilla ended her career. Her husband, Helmut Rulofs, released several songs under the pseudonym Chris Denning and worked for Frank Farian. Under the pseudonym G. Winger she wrote the song 'I see a boat on the river' for Boney M. Later, she founded the group Vanilla.
