Lighthouse
Appeared at the Isle of Wight Festival in 1970
Lighthouse is a Canadian rock band formed in 1969 in Toronto which included horns, string instruments, and vibraphone; their music reflected elements of rock music, jazz, and classical music.
The group was originally scheduled to play at Woodstock but they decided not to, fearing that it would be a bad scene. Years after, many of the group members said they regretted the decision.
