As someone not that familiar with LB, I thought it sounded very much like Neil Finn’s typical singing style. The “yelps” going into a phrase are something he’s definitely done plenty before. I did note that he was using more of a full-throated, wide vibrato which he seems to do less and less of these days in his own work, but again, nothing foreign to his toolbox.
Others have commented that MC should have used a Les Paul. Two thoughts...nobody noted that he did, in fact change to a Les Paul (I believe) for the solo. But also, why should he be totally beholden to what LB did? If he’s just going to repeat the past, why would he even do this? They can get a session player for that. I think he and Neil are hopefully free to diverge from tradition and bring some of themselves to this project...which was ostensibly why they were hired.
