I know these tv show "talents" generally get a bad press, and I know she's a bit of a pound shop Whitney, but I think she put her own mark on this tune and did a decent job.
I love The Jam's version of Get Yourself Together on the Extras album. I prefer it to the Small Faces original. It transpired that Paul Weller re-recorded the vocal track and dubbed it onto the 1980 recording that appears on Extras.
