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.
The song differs from earlier Van Halen songs in that it is driven by a rolling synth line (played on an Oberheim OB-Xa), although the song does contain a guitar solo, which was spliced together from multiple takes. David Lee Roth dedicated the song to martial artist Benny Urquidez, of whom he was a student.
