The trouble with the kind of referendum Owen Smith seems to be calling for is that it's not clear what,d be on offer. Basically there are three ways to go - there'd be aceepting whatever cobbled up deal the government might manage to get ( if in fact suchh couLd be obtained), there'd be going for pure Brexit, no dealls, and there,d be 'let's call the whole thing off", and staying in the EU.

I suspect that last would probably be the option of preference for most people - but it doesn't seem likely it'd be on offer.

If I had my choice I'd go for a fresh in out vote, but this time with EU imigrants having the same right to vote as Commonwealth immigrants, and a vote for 16 and 17 year olds. Both of which they had in the Scottish independance vote. After all, those are the two groups with most at stake in this.
