Following this, numerous small reunion projects began to appear. In 1991, a line-up featuring Robertson and Downey performed with Bobby Tench on lead vocals, ex-Grand Slam member Doish Nagle on guitar and Doug Brockie on bass. They toured Ireland briefly with a series of "An Evening of Thin Lizzy" concerts. In August 1994, Downey, Bell, Robertson and Wharton held a tribute concert in Wolverhampton, together with tribute bands Limehouse Lizzy, Ain't Lizzy and Bad Habitz. Another version of Thin Lizzy was formed later that year by John Sykes (now also performing lead vocals) with Downey, Gorham and Wharton, and with bass parts played by Marco Mendoza, who had played with Sykes in Blue Murder from 1991–93. The tour was advertised as a tribute to Phil Lynott. This line-up also played at the Vibe for Philo gig on 4 January 1996, with a number of other notable musicians including Eric Bell, Midge Ure, Henry Rollins, Therapy? and Joe Elliott and Rick Savage from Def Leppard.
In 1994, a collection of Thin Lizzy tracks from the BBC Radio 1 Peel Sessions was released, and yet another compilation album was brought out in 1996, called Wild One: The Very Best Of Thin Lizzy. This was successful, although it did not feature the title track, "Wild One".
On 20 August 1996, Rude Awakening bassist Robert Ryder held "A Celebration of the Life of Philip Lynott" at the Palace in Hollywood, California at the request of Lynott's mother, Philomena, to commemorate both Phil Lynott's birthday and the tenth year of his passing. Philomena Lynott, her partner Dennis Keeley, and Smiley Bolger (Ireland's Vibe for Philo promoter) were flown to Los Angeles by Ryder to make a personal appearance at the show. It featured concert performances by Rude Awakening, Billy Sheehan, Rudy Sarzo, John Norum, Carmine Appice, Phantom Blue, Soma, producer Roy Z and his band the Tribe of Gypsies, Mark Ferrari, Oslo, Bang Tango, Stash, Iron Cross and Irish singer-songwriter Mark Dignam.
