I can’t say for sure as I have not been able to watch it myself, but I have a feeling that under the right circumstances (which may or may not include a Cyworld account) it is possible to hear and see Whale perform some W&Whale music accompanied by nothing but an acoustic guitar here.
update: Thanks to Nathan Scott I now know that the video mentioned above has been available in 6 parts on YouTube for almost a week:
1. Whale Song
2. Stardust
3. Under The Weather (KT Tunstall cover)
4. Give Me One Reason (Tracy Chapman cover)
5. People Get Ready (The Impressions cover)
6. Hand in My Pocket (Alanis Morisette cover)
You can also see them on YouTube, in 6 parts…
It’s always nice seeing someone who can sing so well also play an instrument well.
