Over the next few years, working alongside Emitt Rhodes, he co-founded the Merry-Go-Round, playing on their records as well as Rhodes' later solo material, and Larson was also one of four percussionists on Lee Michaels' album, Fifth -- which included the hit single Do You Know What I Mean -- before taking the unusual step of rejoining the Grass Roots. The latter group, following the departure of the Bedouins members, had been reconstituted successfully with the ex-members of a band called the 13th Floor and enjoyed a string of more than a dozen major chart hits, radio-friendly pop/rock, and pop/soul songs that often got even heavier airplay than their chart positions indicated -- Larson rejoined in time for their last couple of years of success before the hit singles ran out. After that, he played in various latter-day incarnations of the band, using the name in the years before bassist/singer Rob Grill formally revived the group. Larson entered the music promotion business in the '80s, while continuing to play occasionally, and in more recent years has made the jump into the film business. ~ Bruce Eder, Rovi
