The Wolfman Jack Show was a weekly half-hour musical variety program which debuted as Here Comes The Wolfman on 5 October 1976 on CBC and ended on 15 March 1977.  It contained 26 Episodes. 

It was headlined by pop-culture hero Wolfman Jack (real name Robert Weston Smith) on a mock-up radio station set. Canadian singers and dancers, actors and performers, plus some of the country's top musicians were in the spotlight throughout the variety entertainment series. In addition to Canadian stars and newcomers, there were also international guest stars. The series ranged from the hectic early days of 1950s rock through the melodic harmonies of the Beatles era to the more lyrical contemporary music of the superstars of the 1970s.

ABBA performed Dancing Queen and Fernando (both in kimonos) and SOS (in blue satin suits). Whilst the performances were recorded at the same time, they were broadcast on separate episodes:

1. 6 November 1976, guests were:
   1. The Bay City Rollers
   2. ABBA - which song(s)?
   3. the puppet troupe The Famous People Players.
      
       
2. 5 March 1977, guests were:
   1. ABBA - which song(s)?
   2. Little Richard
   3. Bobby Curtola
   4. Sharon Lee Williams.

There was a repeat of Dancing Queen which was sandwiched between guests Johnny Rivers and The Shirelles in that particular episode.  Which broadcast date?

Wolfman Jack died on 1 July 1995 aged 57.
