I was at this show in Hyde Park.
The lineup was:
Steve Boyce Band
Robert Randolf + his family band
01. Tell The Truth
02. Key To The Highway
03. Hoochie Coochie Man
04. Outside Woman Blues
05. Here But I'm Gone
06. Why Does Love Got To Be So Sad
08. Rockin' Chair
09. Motherless Child
10. Travellin' Riverside Blues
11. Running On Faith
12. Motherless Children
13. Little Queen of Spades
14. Before You Accuse Me
15. Wonderful Tonight
18. Crossroads (with Sheryl Crow John Mayer and Robert Randolph)
I did enjoy this, although only know a handful or Eric Clapton's songs, I actually knew more of Sheryl Crow's songs.
Steve Boyce Band average,
Robert Randolf, different and entertaining
Jason Mraz, really enjoyed this mellow acoustic set
John Mayer, not my cup of tea, but his music is good
Sheryl Crow, highly enjoyable, knew most of the songs
Eric Clapton, the show didn't properly light up until Wonderful Tonight, that's when the atmosphere started to get really good. I found myself almost bored through the middle of one song in particular which was extended to 12 minutes, i don't know which because im not highly familiar with Clapton's material.
This is the first show I've ever been to in London, and if given the chance I'd go to another. Unfortunately I had a flight back the next night so didn't get to see The Police (who i'd have seen in a gunshot instead).
