"Round Up" is a song by American rapper Lady May, featuring American R&B singer Blu Cantrell. Released as a single in June 2002, the song was supposed to be the lead single from May's debut album, May Day, but the album has never been released. The single performed moderately in the U.S. urban market, peaking at number ninety-three on Billboard's Hot R&B/Hip-Hop Songs the week of July 27, 2002. "Round Up" never appeared on any albums except on non-U.S. pressings of Cantrell's second studio album, Bittersweet, released in 2003.
Round Up is an amusement ride consisting of a circular horizontal platform with a vertical cage-like wall around the edge. The platform is attached to a motor on a hydraulic arm. The ride starts out by spinning until the centrifugal force is enough to push riders against the wall. Then the arm raises the horizontal platform to a vertical position in which riders, instead of spinning horizontally, are now spinning almost vertically.
The ride spins for a predetermined cycle until an automatic timer releases the hydraulic fluid from the arm, causing the platform to return to its horizontal position. The operator may be required to manually control the spin of the ride such that its exit aligns correctly with the exit gate. Most Round Ups require the rider to be at least 42 inches tall.
In the United Kingdom, this ride is commonly known as the Meteor or Meteorite. The first such ride to arrive in that same country was with Rose Brothers in the 1950s and it came from Germany.
Although Hrubetz examples, exist in the United Kingdom other common makers, including Cadoxton and Sam Ward.
