This is Lawson's poem "The Lights of Cobb & Co" set to music by Gerry Hallom (he of the lovely tune for "The Outside Track"!) : https://www.youtube.com/watch?v=8A4GVj_CZIw

This is the Lionel Long track mentioned earlier, "The Ballad of Cobb & Co" : https://www.youtube.com/watch?v=-D81-ojOKSc

This is "Spirit of Cobb & Co" by Dave Reynolds : https://www.youtube.com/watch?v=WAmP7CFMalw

The Cobb & Co ride at Longreach (apparently the last one to go at full tilt!). I remember years ago, riding next to the driver of one in a "Pioneer Village" - possibly in Victoria - and that was alarming enough!!! :
