There was a time in the 70s that when you bought a Rijam brand school diary in Holland you were given an exclusive, thick, gold flexi containing four superb Dutch bands. The A-side holds "Mammoth" by KAYAK and "The Smile" by BRAINBOX, whilst the B-side has "Jumbo" by DIZZY MAN'S BAND and "Hocus Pocus" by FOCUS. A very rare item I have only ever come across once!
