Smith appears in the film Wayne's World as a member of Alice Cooper's band, performing "Feed My Frankenstein".[5] Smith toured with Cooper from 1991 to 1994.[6]
In 1993 Smith joined a reformed Rainbow with Ritchie Blackmore. Greg remained with the group until 1997, when they disbanded.[7] From 2008 to 2011, he and a few other members from Rainbow, including lead singer Ritchie Blackmore's son Jürgen, were in Over the Rainbow.
Greg filled in for Jon Rogers, from Blue Öyster Cult, for a few concerts in summer 1995.[8]
Greg joined the touring band for Ted Nugent in 2007. Smith recorded six albums with Ted, and in concert played the bass guitar and also sang the backing vocals originally performed on records by Derek St. Holmes.
He announced that he was leaving Nugent's band in 2022 with the announcement: "After 16 years, and many laughs and amazing times with one of the greatest guitarists to ever pick up the instrument, I am saddened to say I will be unable to be a part of Ted Nugents final tour Adios MOFO. It was a difficult decision but one that I really had no choice in. With Ted no longer touring I had to accept an offer from a tour that will continue for the next several years. I tried to get someone to cover for me for the 2nd half, so I'd be able to do Ted's tour, but I was unfortunately unable to. I would like to thank Ted for 16 years of some of the most serious, intense, aggressive, and fun music I've played in my career… I'll miss you guys this summer! Kick Ass! I'd also like to thank Doug Banker, Bob Quandt, Frank Trzaskowski, Toby Nugent & the crew past & present. Shemane Nugent, and the extended Nugent family for just being awesome people… Ted and band mates past & present during my 16 years, Derek St. Holmes, Wild Mick Brown, & Jason Hartless. Thanks for an Amazing Ride! See you all down the road!"[12]
