In 1984, Van Halen were on a roll. Their "1984" album became their highest charting album, hitting #2 on the Billboard Top 200. Not only that, the first 3 singles from the album all went into the Top 15 on the Billboard Hot 100 as well.
"Panama" was the 3rd single to come out from the album. A 4th single, "Hot For Teacher", would emerge later in the year with it's notorious music video getting maximum airplay on MTV.
Unfortunately, singer David Lee Roth, would part ways with the rest of the band at the end of the year. But he's back with the band these days and they continue to tour even to this day.
