4 chord songs

Hi to you all from the UK. I thought this might be useful. I am a beginner and have been playing for 9 months. Thanks Josh for all your videos and help on this forum.

My thought is… people might like to listen to this video https://www.youtube.com/watch?v=oOlDewpCfZQ and then either try and listen to the individual songs and try and swap root notes at the correct time. (D, A B and G) or try and play a triad plus 1 more note in at each change. So (D major, A major, Bminor ang G major). Some sort of backing track at various speeds would help. Thoughts Josh plus the community? Thanks Richard (Shropshire in UK)
