Music: Piero Umiliani
Piero Umiliani composed the soundtrack for Svezia, Inferno e Paradiso/Sweden, Heaven and Hell/Schweden - Hölle oder Paradies/ Sverige - Himmel eller helvete. It is typical laid-back lounge-style jazz-pop, á la 60s and 70s, often heard in European exploitation flicks of that era.
(The soundtrack of course contains the famous song "Mah-na-Mah-na"....)
