Loved the episode. Listening a second time now. V keen to hear more on this topic.

With existing mulitsig, we have to keep a copy of the redeem script or all the xpubs in case one of the keys are lost.

If one of the keys of say a 2 of 3 Frost multisig private key is lost, is it possible to have access to spend funds if only have 2 of the private keys and no redeem script or xpub of lost key?

Sounds like you can as there is no redeem script? Is that correct?
