I Feel The Earth Move by Carole King from the classic album, Tapestry.
I've been listening to this album again this week, it's totally one of those LP's where each song is a total classic. It also helps that Carole is one of the greatest songwriters ever with a beautiful voice too. This clip is from the short lived BBC In Concert series, BBC four played a few of these shows over the last couple of years when doing a singer songwriter season including Neil Young doing Harvest, James Taylor, Joni, The Eagles etc. I have seen a list of other people that featured in this series including Argent, Roxy Music, Stone the Crows, Traffic, Pretty Things, Badfinger and many more, but knowing the beeb these have probably all been deleted or recorded over!
