There was a set from the late 90s, early 2000s, possibly a sensation white, or something of the sorts, which had a remix of 'I wont let you down'. I don't believe I remember it being a vocal version, but the highs were clearly playing the notes of 'I.... I wont let you down... wont let you down again...' I've tried really hard to track it down, but can only find heavy vocal versions which aren't even close. Please please give me any leads!
