The Turn of a Friendly Card is the fifth album by progressive rock band The Alan Parsons Project, released in 1980. The album has a 16-minute title piece, which was broken up into five tracks (except the West German CD pressing), with the five sub-tracks listed as sub-sections. The Turn of a Friendly Card spawned the moderate hits "Games People Play" and "Time", the latter of which was Eric Woolfson's first lead vocal appearance.
"The Gold Bug", which references the same-titled short story by Edgar Allan Poe, includes a whistling part by Parsons, who imitates the style of Ennio Morricone's legendary Spaghetti Western film themes, and wordless vocals by Rainbow, while the main theme is played on an alto saxophone. The saxophone player, originally credited as Mel Collins, is instead credited on the liner notes for the remastered edition as "A session player in Paris whose name escapes us"; this refers to the fact that the saxophone part is a composite of several separate takes. Similarly, the accordion part on "Nothing Left to Lose" is credited in the liner notes to "An unidentified Parisian session player". Also on "The Gold Bug", the newer liner notes credit a "Harmonized Rotating Triangle" to drummer Stuart Elliott. This refers to the phasing sound effects heard throughout the rhythm-free introduction to the piece.
