Input: Consider Input: Question: What song on Hammer's debut album samples a song by the same name from BB King? Passage:Before Hammer's successful career (with his mainstream/commercial popularity lasting approximately between the mid-1980s until the late-1990s) and his "rags-to-riches-to-rags-and-back saga", Burrell formed the Christian rap music group Holy Ghost Boys. Some songs produced were called "Word" and "B-Boy Chill". "The Wall", featuring Burrell (it was originally within the lyrics of this song he first identified himself as "K.B." and then eventually M.C. Hammer once it was produced), was later released by Jon Gibson (aka "J.G."). This was Contemporary Christian music's first rap hit ever (by anyone), in particular by a Caucasian (Gibson) and/or from a duo. The track appeared on Gibson's album Change of Heart (1988), and "Son of the King" showed up on Hammer's debut album Feel My Power (1987) as well as the re-released version Let's Get It Started (1988). Burrell, along with Tramaine Hawkins, performed with Gibson's band doing several concerts in various venues such as the Beverly Theatre in Beverly Hills.

Input: Consider Input: Question: Who is currently in charge of the company that commissioned the construction of MS Al Andalus Express? Passage:MS Al Andalus Express (formerly Nord Pas-de-Calais) is a freight ferry owned by Eurotunnel and operated by FRS Iberia/Maroc. She was built in 1987 by Chantiers du Nord et de la Mediterranee, Dunkirk (Yard No 325) for Societe Nationale des Chemin de Fer Francais (SNCF), Paris as a multi-purpose passenger and roll-on roll-off ferry for lorries and railway vehicles. After the introduction of Eurotunnel there was no need for a train ferry, so SNCF was losing money running her. She was acquired by SNAT and Stena Sealink in 1989, which operated the Nord Pas-de-Calais until 31 December 1995. From 1 January 1996 SNAT operated as SeaFrance. The vessel was renamed SeaFrance Nord Pas-de-Calais. SeaFrance operated until November 2011, and was liquidated on 9 January 2012. Eurotunnel won the bid for the three of the former SeaFrance vessels the original name of the vessel was restored, dropping the SeaFrance prefix. MyFerryLink started running on 20 August 2012, although Nord Pas-de-Calais joined in November 2012 following a refit. Following MyFerryLink's cessation of operations, mostly cited due to financial issues, the ferry was used directly by Eurotunnel to carry hazmat cargoes that are not allowed on regular train services.
