Hear N Aid - "Stars" is an outstanding song. Shortino is on it, among Dio, Halford, Tate, Vince, etc.
I absolutely love that song. Fortunately, Vince (Neil, I assume) did not get any of the lead vocals. He (along with Mick Mars from Crue) was in the backing vocal choir. The leads were done by RJD, Halford, Kevin DuBrow, Eric Bloom, Tate, Dave Meniketti, Don Dokken and Paul Shortino. I actually thought Meniketti also did one of the guitar solos, but not so. Those were done by Vivian Campbell, Carlos Cavazo, Buck Dharma, Brad Gillis (my personal favorite), Craig Goldy, George Lynch, Yngwie Malmstee, Eddie Ojeda, and Neal Schon. I love the story about how Dave Murray and Adrian Smith decided (while flying in during the middle of the World Slavery Tour) NOT to do solos and, instead, do the harmony licks under the chorus.
