I know many were dissapointed that they didn't perform DWAS, but personally i'm ok with that decision since we got full attention on "Abracadabra" release.
That said, their cover of "California Dreamin'" was sublime. Gaga really captured that 60s vibe so well and now I want a full LadyMars EP.
Also if you're not aware of the folky/soul group- The Mamas and the Papas/Cass Elliot then here's ya go.
