OK, just listened to two sets, Tiesto @ OneBigWeekend (2004) and Tiesto @ Events Hall (2004)....both sets contain the songs "Interstate - I Found U" and
"Ridgewalkers featuring El - Find (Andy Moor Remix)"

Nopw in the tracklists for the two sets I think the titles are switched, i.e. one track is named one of the above in one tracklist and the other in the other tracklist, since both contain vocals can someone clarify for me which one is which through the vocals (or otherwise)......
