Thanks GedKen and Reg,
GedKen, the Melody Maker interview sounds like an intriguing read. I don't suppose it is online anywhere? I don't think its in the Harleyfanzone scrapbook.
Thanks for the reminder of the Hans-Peter Janssens version Reg, and GedKen for the Patricia Paay version - I've added a "Cover Versions" section to the article now with them both mentioned.
Reg, the source of the chart positions on the article are that of dutchcharts.nl and ultratop.be which in accordance to Wikipedia's guidelines are the accepted, most accurate sources of chart positions in Europe. However I do sometimes wonder if some positions are missing from certain songs, mainly in particular countries as Belgium, as I know that there are various charts, and some of which may not be easily obtainable.
There are some conflicting sources though as
www.flanders-hitparade.net/ has Sebastian listed as peaking at #4, although ultratop.be is a more reliable source of the two. It could very well be that the song did actually peak at #1, but there would need to be an official source to reference it.
