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 students were given the assignment to write and recite a poem for the class, and each of them simply recited pop/rock song lyrics. Chris Farley recited lines from Van Halen's Jump, and Hartman's character interpreted it as a suicidal cry for help (as in someone jumping off of a building.)
