The band was then rejoined by Kaminski, Clark and Morgan, adding Martin Smith on bass guitar, and proceeded to perform a small number of live ELO performances in 1986, including shows in England and Germany along with US appearances on "American Bandstand", "Solid Gold", then at Disneyland that summer. The Birmingham Heart Beat Charity Concert 1986 was a charity concert organised by Bevan in ELO's hometown of Birmingham on 15 March 1986, and ELO performed. A hint of Lynne's future was seen when George Harrison appeared onstage during the encore at Heartbeat, joining in the all-star jam of "Johnny B. Goode". ELO's last performance for several years occurred on 13 July 1986 in Stuttgart, Germany playing as opening act to Rod Stewart. With Lynne no longer under contractual obligation to attend further scheduled performances, ELO effectively disbanded after that final show in Stuttgart in 1986, but there was no announcement made of it for the next two years, during which George Harrison's Lynne-produced album "Cloud Nine" and the pair's follow-up (with Roy Orbison, Bob Dylan and Tom Petty as Traveling Wilburys) "Traveling Wilburys Vol. 1" were released.
