"
Mr. Roboto" is a song written by
Dennis DeYoung of the band
Styx, and recorded on the Styx album
Kilroy Was Here. It was also released as a 45 RPM single in a 4:44 radio edit, which has the
synthesizer intro removed (available on "Greatest Hits" released by PolyTel in Canada in 1982), with the song "
Snowblind" (from their previous album
Paradise Theatre) as the
B-side. In Canada, where they were generally more popular than in their native U.S., it went to #1 on the
RPM national singles chart, becoming their third single to top the charts in that country (following "
Babe" in 1979–80 and "
The Best of Times" in 1981). In the U.S., it reached #3 on the
Billboard Hot 100.
