Ross and three bandmates formed Daddy Cool in 1970 and toured Australia. In early 1971 they performed at the Myponga Festival in South Australia. Concert footage of their performance of "Eagle Rock" shows a pregnant Wilson in the front row (from 1m.43sec, right hand side of the screen). Both Pat (visibly pregnant) and Ross also appear in Chris Löfvén's short film "Part Two - The Beginning". The Wilsons' son Daniel was born just as "Eagle Rock" reached No. 1 on the National singles charts. At about this time, Wilson started writing her column for "Go-Set" taking over an advice column called "Dear Lesley Pixie" and using the pen-name "Mummy Cool". She also appeared in a documentary about the band, singing with Rock Granite and the Profiles, a group which featured future members of Jo Jo Zep and the Falcons.
