 The song "Only You Know and I Know" reached number #42 on the "Billboard" charts in the US and was the record's major commercial success.About 30% of the records were produced in so-called "marble vinyl", a swirled mix of pink, brown and beige, rather than the usual black vinyl.The original record jacket is a tri-fold with a half-pocket on the inside to hold the record (originally issued without a paper inner sleeve).
