Who Have AC/DC Supported

[Starman 2112]

Last night I was lucky enough to attend the secret AC/DC gig at the Hammersmith Odeon (or Carling Apollo as it is now called). On sale at the gig was a T- Shirt titled 'Hammersmith We Salute You' ; on the reverse of the shirt was listed all the dates that AC/DC had played at the Odeon. What I want to know is did AC/DC play all those dates as the headline act or not. If they were the support band, who did they support.
