[he] is a detail man – the temperature, the location , foliage". <P2-S9>  On 26 March 2006 Kelly performed at the Commonwealth Games closing ceremony in Melbourne, singing "Leaps and Bounds" and "Rally Around the Drum". <P2-S10>  In February 2009 Patience Hodgson (of The Grates), Glenn Richards and Kelly performed "Leaps and Bounds" at the Myer Music Bowl for SBS-TV's concert RocKwiz Salutes the Bowl. <P2-S11>  On 29 September 2012 Kelly performed "How to Make Gravy" and "Leaps and Bounds" at the 2012 AFL Grand Final although most of the performance was not broadcast on Seven Network's pre-game segment. <SEP> <P3-S0> The VH1 Rock Honors were an annual ceremony paying homage to bands who influenced the sound of rock music. <P3-S1>  The events began in 2006, and the final event took place in 2008. <P3-S2>  The general format of each show is for modern bands to "pay tribute" to classic greats of the rock/metal world (by covering a song of theirs), after which time the artist being paid tribute to plays multiple songs. <P3-S3>  The 2006 and 2007 shows featured four inductees each, whereas the 2008 show featured one (The Who), albeit with multiple bands paying tribute. <P3-S4>  The shows were directed by David Mallet and produced by Paul Flattery. <P3-S5>  Currently, VH1 has no plans for a CD or DVD release of any show.
