Traffic - You Can All Join In INSTRUMENTAL 

Another one of Dave Mason's infamous whimsical psychedelic songs with the band, this track opens their 1968 self-titled album. Not long after Dave Mason's first quitting of the band (he would quit 3 times within a 5-year span), the remaining trio convinced him to rejoin to help them record their sophomore LP. Mason would end up writing 5 of the album's 10 songs (one song co-written with drummer Jim Capaldi), including one of Traffic's signature songs, "Feelin' Alright?"
While Winwood, Capaldi, and Wood were always a tight-knit group, Mason often found himself the outcast who wrote songs with the rest of the guys weren't total fans of.
