David Sanger is frequently partnered by Hans Fagius from Sweden for Organ Duet Concerts.

Hans Fagius, born in Norrköping, Sweden, in 1951, was taught by the organists Nils Eriksson and Bengt Berg before studying at the Stockholm College of Music with Alf Linder, under whose guidance he obtained his soloist's diploma in 1974. He subsequently studied for a year in Paris with Maurice Duruflé.

In recent years, on the basis of private study, he has devoted himself increasingly to Baroque music, trying to approach the music on its own terms under the inspiration of scholarship in this field. On two occasions he has won prizes in international organ competitions and since the beginning of the 1970s he has given numerous recitals throughout Europe, in the USA and in Australia. He has also made radio recordings in a number of countries.

He has taught at the Stockholm and Gothenburg Colleges of Music and since 1989 is Professor at the Royal Danish Conservatory in Copenhagen. He has made numerous recordings on the BIS label, and he performed the complete organ works of J S Bach in two series of recitals in Malmö and Copenhagen, in a total of 24 recitals.
