[{"role": "system", "content": "Van Halen is an American hard rock band formed in Pasadena, California, in 1972. From 1974 until 1985, the band consisted of guitarist Eddie Van Halen, vocalist David Lee Roth, drummer Alex Van Halen, and bassist Michael Anthony. The band went on to become major stars, and by the early 1980s they were one of the most successful rock acts of the time. \"1984\" was their most successful album. The lead single, \"Jump\", became an international hit and their only single to reach number one on the \"Billboard\" Hot 100. The following singles, \"Panama\" and \"I'll Wait\", both hit number 13 on the U.S. charts. The album went on to sell over 12 million copies in the U.S. alone. In 1985, the band replaced lead singer David Lee Roth with former Montrose lead vocalist Sammy Hagar. With Hagar, the group would release four U.S. number-one albums over the course of 11 years. Hagar left the band in 1996 shortly before the release of the band's first greatest hits collection, \"Best Of \u2013 Volume I\". Former Extreme frontman Gary Cherone was quickly recruited as lead singer to replace Hagar, and \"Van Halen III\" was released in 1998. Cherone left the band in frustration in 1999 after the tour due to the poor commercial performance of the album.\n"}, {"role": "user", "content": "I love the band Van Halen and still listen to them regularly"}, {"role": "assistant", "content": "I love van halen,  Van Halen is an American hard rock band"}, {"role": "user", "content": "Yes and they have been around for a long time"}, {"role": "assistant", "content": "Yeah they  formed in Pasadena, California, in 1972."}, {"role": "user", "content": "Oh I did not realize it was that long ago "}, {"role": "assistant", "content": "Yeah and The band went on to become major stars, and by the early 1980s "}, {"role": "user", "content": "I wonder how many albums they have sold?"}, {"role": "assistant", "content": "I think 1984 was thier best album"}, {"role": "user", "content": "Oh yes  I agree with that"}, {"role": "assistant", "content": "I read in a magazine that The lead single, \"Jump\", became an international hit "}]
