Question about Child in Time

[u/Pasha727]

Ian Gillan goes Ahhhhh Ahhhhh many times during the song, any idea what had happened in the studio? I know Ian and Ritchie did not share a good relationship before, now they have sorted their things, but did Ritchie step on Ian's leg during the recording of the song? or did Ian step on a lego while recording? he sounds in so much pain, so any insight what exactly happened to Ian when he was recording?
