I have been following, though not very closely because time don't permit me to, the current American Idol competition. SH told me about Jason Castro's ukelele-version of "Somewhere Over the Rainbow" and I went "Oh, dear". When I watched it over Youtube.com and saw him with the ukelele, I went "Oh, no". But as he sang on, I was won over. He was fantastic.
Here is the late Israel Kamakawiwo'ole's original version of the arrangement that Jason used, which I fell in love with. There is such a gentleness in his voice.
This year's Idol Gives Back is being carried out separately from the competition proper, due to possible conflict and when I found out that they did Darlene Zschech's "Shout to the Lord" to close the show, I had to check it out in Youtube.com. It was well done, though they did substitute the opening, "My Jesus, My Saviour" with "My Shepherd, My Saviour".
