Question: Which of the two rock musicians that appeared in "The Secret Policeman's Ball" recorded an album first? Passage:Ball co-founder Cleese and Jones had an involvement (as performer, writer or director) in all four Amnesty benefit shows, Palin in three, Chapman in two, and Gilliam in one. Idle did not participate in the Amnesty shows. Notwithstanding Idle's lack of participation, the other five members (together with "Associate Pythons" Carol Cleveland and Neil Innes) all appeared together in the first Secret Policeman's Ball benefit—the 1976 A Poke in the Eye held at Her Majesty's Theatre in London's West End—where they performed several Python sketches. In this first show, they were collectively billed as Monty Python. Peter Cook deputised for the errant Idle in a courtroom sketch. In the next three shows, the participating Python members performed many Python sketches, but were billed under their individual names rather than under the collective Python banner. The second show featured newcomer Rowan Atkinson and Scottish comedian Billy Connolly. The Secret Policeman's Ball were the first stage shows in the UK to present comedic performers (such as Monty Python and Rowan Atkinson) in the same setting and shows as their contemporaries in rock music (which included Eric Clapton, Sting and Phil Collins). After a six-year break, Amnesty resumed producing Secret Policeman's Ball benefit shows which were held at the London Palladium in 1987 (sometimes with, and sometimes without, variants of the iconic title) and by 2006 had presented a total of 12 such shows. The shows since 1987 have featured newer generations of British comedic performers, such as Stephen Fry, Hugh Laurie, and puppets from the satirical TV show Spitting Image, with many attributing their participation in the show to their desire to emulate the Python's pioneering work for Amnesty. Cleese and Palin made a brief cameo appearance in the 1989 Amnesty show; apart from that, the Pythons have not appeared in shows after the first four."

Question: Who is younger between the two creators of the South Park series? Passage:South Park is a first-person shooter adventure video game based on the American adult animated sitcom of the same name. The game was developed by Iguana Entertainment and published by Acclaim Entertainment for the Nintendo 64 in 1998 for North America and in 1999 for Europe. It was later ported to Microsoft Windows in 1999 and released in North America only. The PlayStation port was developed by Appaloosa Interactive in 1999. A Game Boy Color version developed by Crawfish Interactive was in development, but it was eventually cancelled due to South Park creators Matt Stone and Trey Parker stating that the game would not be fitting on the Game Boy Color as that console was marketed towards children. However, they did keep a few copies of the Game Boy Color version to commemorate what was originally started as the first South Park game. Despite the Nintendo 64 version's positive reception, the PC and PlayStation versions of South Park were panned by critics. A Sega Dreamcast version was planned for a 2000 release, but was cancelled during development for unknown reasons. In 2018, a ROM image of the Game Boy Color version was leaked online.
