Accurate Measurement of Flammable Gases. Combination instruments provide the flexibility to do general-purpose safety monitoring, as well as detection of very high levels of flammable gases and vapors. TODAY there are a variety of sensors used to detect flammable gases.
I saw Van Halen on the 1984 tour, there was no extra keyboard player. Ed played some keyboard on the intro into Jump and some in the middle, but stuck with the guitar for the solo. He did a solo keyboard pice as well seperately.
By that time, bassist Michael Anthony had been replaced by guitarist Eddie Van Halen's son Wolfgang Van Halen, meaning the 1984 Nuremberg show was the last time the classic lineup ever played together in public. The show came near the end of the biggest year of Van Halen's career. Their album 1984 produced Jump, Hot for Teacher and Panama, all of which were in heavy rotation on MTV and radio. They hit the road hard, playing 109 shows across nine months. They should have been on top of the world, but long-simmering tensions between Roth and the Van Halen brothers, Eddie and drummer Alex, became too much and they parted ways months after the tour ended.
