John's guest on Mystery Train's Sunday Service was Norwegian musician Susanna, the woman behind Susanna and the Magical Orchestra.

Her ethereal and sometimes dark interpretations of songs by Joy Division and Dolly Parton belie her early musical interests in good old pop music. She talks about writing her own music, how she chooses songs to interpret, working with Will Oldham and chooses music from many great women including Bjork, Sidsel Endresen, Radka Toneff and of course Whitney Houston.

Tune into next Sunday's Mystery Train this Sunday (October 21st) at 7pm on RTÉ lyric fm, where woodwind instrumentalist, composer and music producer Seán Mac Erlaine will be spinning his favourite tracks.
