Who's Who

Who's Who

Who's Who is the alias of twin brothers Christopher Saint Booth and Philip Adrian Booth. The pair work in music in the 1980s, and many of their recordings are sent to adult film producers for use in their films. They are associated with the song Ulterior Motives, which is also known to listeners as Everyone Knows That or “EKT” after it circulates as a lost song before being identified in the adult film Angels of Passion.

Lostwave identification

The track becomes a viral subject of search under the name Everyone Knows That before its discovery as Ulterior Motives by Who's Who. That identification places the duo within the lostwave scene as the act behind one of the best-known examples of the format.

Later activity

After the search and identification of the song, Who's Who reunite and work on a rerecorded and remastered album of songs they never release in the 1980s.

Christopher Saint Booth

Christopher Saint Booth also has a solo career, composing horror film soundtracks and ambient synth albums. His solo release SkyPolar appears in 2024.
