Question: What substance was the helmet gilded with? Passage 1:And in any case, people in Texas came to identify with the song. The work of the Austin-based group Asleep at the Wheel helped to keep popular knowledge of Wills going, and they collaborated with Clint Black on a new version of "Bob Wills Is Still the King" on a 1999 tribute album Ride With Bob. Another recording of the song by Asleep at the Wheel, this time in collaboration with Waylon's son Shooter Jennings together with Randy Rogers and Reckless Kelly, appeared on the 2015 effort . The song itself is collected on several Jennings live sets, compilations, and box sets, including RCA Country Legends (2001 compilation, includes studio version),  Live from Austin, TX (recorded 1989, released 2006), and Nashville Rebel (2006 box set including studio version). Perhaps the most unexpected appearance was a performance by The Rolling Stones in Austin in 2006 during their A Bigger Bang Tour. Their arrangement featuring Ronnie Wood playing pedal steel guitar was captured on their 2007 The Biggest Bang concert DVD release.
 Passage 2:Pol became the second wife of John Paul Getty, Jr. on 10 December 1966. She was married in a white miniskirt, trimmed with mink. The Gettys became part of Swinging London's fashionable scene, becoming friends with, among others, singers Mick Jagger of the Rolling Stones and his girl-friend Marianne Faithfull. Faithfull has recounted her apprehension, through "ingrained agoraphobia", about an invitation to spend five weeks with the Gettys in Morocco ("but for Mick this is an essential part of his life") and how, after splitting from Jagger, she took up with Talitha Getty's lover, Count Jean de Breteuil, a young French aristocrat (1949–1971). Breteuil supplied drugs to musicians such as Jim Morrison of The Doors, Keith Richards, and Marianne Faithfull, who wrote that Breteuil "saw himself as dealer to the stars" and has claimed that he delivered the drugs that accidentally killed Morrison less than two weeks before Talitha's own death in 1971. For his part, Richards recalled that John Paul and Talitha Getty "had the best and finest opium".
 Passage 3:The tomb was originally a monumental temple at Golyama Kosmatka Mound, built in the second half of the 5th century BC. After extended use as a temple, at the later part of the 3rd century BC, Seuthes lll was buried inside. The sarcophagus-chamber contained personal belongings that were necessary for the afterlife of the King. It includes knee pads, a gilded helmet with images, leather armour with a collar (plastron made of golden threads), a large sword and spears. There are bronze vessels, and three big ceramic amphora which were filled with thick Thracian wine. The floor and the ritual bed are covered by a carpet woven in gold thread. The total weight of the gold including all the objects is more than one kilogram. There are thirteen gold appliques for horse halters with images of human, animals and plants - objects which are rare in Thracian archaeology. Another two rectangular objects are golden with figures of standing warriors, used as a decoration for the sword sheath. There is a massive circular decoration for the King's armour. The handle of the rod is also golden. In the grave are placed golden vessels with two handles for drinking wine, also called kiliks, and a remarkable golden wreath with twigs, leaves and acorns and many other items.
