I don't know, I found it painfully evident that various singers on the CSR were recorded at different times/countries/whathaveyou (and sometimes different tempos, which is even more unfortunate). Especially, I think the (kind of lame) LA students undermine how brilliant Anthony Warlow was as Enjolras.
I'm also not the hugest fan of Tracy Shayne's Cosette (or the rationale that because Gary Morris was Valjean, that the woman playing Cosette had to be American as well. What?).
The CSR is a great concept, but the execution sometimes leaves something to be desired.
