At times, the duo were also known as Whyyou (taking lead from first letters of their names "why" (Y) for Yepha and "you (U) for UFO).
[2] Their album Ingen som os in 2006 brought further success to the hip hop duo.
The group had previously appeared on MC Clemens' second album, Den anden verden as a collective Kælderposen (alias Kældersquad) which included UFO Yepha, Rune Buoy, Jot, LX, Jesper Drejer, Ole R and DJ Rescue.
Meanwhile, Yepha is cooperating with various artists and most notably Morten Hampenberg & Alexander Brown being featured in a number of their releases including "Skub til taget" (2009) and "Det stikker helt af" (2011) and "Klovn" (also in 2011).
