Andrew duetted with Rainhard Fendrich on Fendrich's Xmas single, Little Drummer Boy/Stille Nacht, Heilige Nacht: released Xmas 1997.
Rainhard is famous as a singing star and actor in Austria and Germany, and asked Andrew to sing with him on a version of "Silent Night" which copied the original idea by only featuring two voices and an acoustic guitar.
"I drove to Rainhard's house in Vienna to record the song and we practiced it in his studio. I learned how to sing it in German but with an Austrian Linz accent, and Rainhard said I sounded too foreign. (He wanted more of a Vienna accent...)"
