Heinz Kiessling

Heinz Kiessling (March 11, 1926 – December 27, 2003) was a German musician, conductor, composer, and music producer, known mainly from his work for popular films and television programs. Kiessling's piece ''Temptation Sensation'' (originally titled ''Haute Couture'') is the theme song for ''It's Always Sunny in Philadelphia'', which is the longest-running live-action sitcom in American television history. The series also uses background music during its episodes from Kiessling, such as ''On your Bike'' or ''Blue Blood'' (originally titled ''Tandem-Holiday'' and ''Pizzicata Milanese'' respectively).
