I played Hodel in Fiddler Jr. last summer
'Now I Have Everything' is cut.
Perchik is in quite a few scenes; slightly more than Motel, but not as many in Tevye. His scenes are all with Hodel, except for one with Tevye.
His only solo singing is two lines in 'Sunrise, Sunset'. He also has a dance solo in 'The Wedding Dance.' (It's actually not really a solo - he dances with Hodel).
If you need anything else, let me know
